Product snapshot

You’re looking at the TOTO® Drake® WASHLET®+ Two-Piece Elongated 1.28 GPF TORNADO FLUSH® Toilet with S5 Bidet Seat, Cotton White – MW7763446CEG#01. This model pairs a proven TOTO toilet platform (Drake® with TORNADO FLUSH® and CEFIONTECT glaze) with a WASHLET+ S5 bidet seat that brings warm water cleansing and seat heating to your daily routine. You’ll get both high-performance flushing and advanced hygiene features in a familiar two-piece configuration.

What’s included and how it’s packaged

You’ll receive the toilet bowl and tank as a two-piece assembly plus the S5 WASHLET+ bidet seat prepackaged for installation. The WASHLET+ connection is designed for a concealed, streamlined look that keeps visible hoses and cords to a minimum so your bathroom feels neater.

Key features at a glance

You’ll appreciate the combination of cleansing, comfort, and cleaning technologies built into this unit. Below is a quick breakdown so you can see core specs and what each feature does for you.

Feature	What it means for you
TORNADO FLUSH® (1.28 GPF)	Powerful circular flushing action that cleans the bowl efficiently while using less water than older 1.6 GPF models.
CEFIONTECT glaze	Ultra-smooth ceramic finish that resists waste sticking and helps make bowl cleaning easier.
WASHLET+ S5 bidet seat	Warm water rear and front cleansing, adjustable temperature and pressure, oscillating and pulsating wash modes.
SoftClose heated seat	Prevents slams and keeps the seat warm for comfort, especially in cooler climates.
PREMIST	Mists the bowl before use to help waste slide off the surface for easier flushing.
EWATER+ wand self-clean	The spray wand self-cleans inside and out using electrolyzed water, reducing the need for manual wiping of the wand.
Air deodorizer & filters	Reduces bathroom odors using an internal filtration system for a fresher experience.
Warm air dryer	Lets you reduce or skip toilet paper for a cleaner finish.
Built-in night light	Soft illumination to guide you to the toilet in low light without turning on the main lights.

Performance and flushing

You’ll notice how flushing performance balances power and economy. The TORNADO FLUSH® creates a circular rinsing action that targets the bowl surface, and combined with the CEFIONTECT glaze the bowl stays cleaner longer. Because the toilet uses 1.28 gallons per flush (GPF), you get solid waste removal while conserving water compared with older 1.6 GPF toilets.

How effective is the 1.28 GPF TORNADO FLUSH®?

You’ll find it effective for daily use; the swirling jets focus cleaning power across the bowl to minimize repeat flushes. If you live in an area with very hard water or heavy use (like a busy household), you may still need an occasional extra flush, but for most users this model handles routine use without trouble.

Noise and speed

You’ll encounter a typical flush sound for a performance toilet — not whisper quiet, but not overly loud either. The flush completes quickly, giving you a fast, reliable clearing action that minimizes the chance of clogs when installed properly and paired with appropriate drain plumbing.

The WASHLET+ S5 bidet seat — cleansing and comfort

You’ll get a high level of hygiene and comfort with the WASHLET+ S5. It provides both rear and front warm water cleansing with adjustable temperature and pressure settings, plus oscillating and pulsating wash modes to suit different preferences. The wand is self-cleaning with EWATER+ treatment that helps keep the nozzle sanitary.

Temperature, pressure, and wash modes

You’ll be able to tune both the water temperature and the pressure to match what feels best for you. The oscillating and pulsating modes give you two different movement patterns — one for a broader area of coverage and one for a massaging sensation that improves cleaning efficiency.

Air deodorizer, dryer, and night light

You’ll appreciate the integrated air deodorizer which reduces odors at the source, and the warm air dryer that can significantly reduce your need for toilet paper. The built-in night light provides a gentle glow so you can use the bathroom at night without bright bulbs.

Comfort, ergonomics, and dimensions

You’ll sit on a standard-height bowl rather than TOTO’s Universal Height, so the rim sits a bit lower than a comfort-height model. The elongated shape gives you more seating area for comfort, and the SoftClose seat prevents noise when the seat is lowered. If you prefer a slightly lower seat compared to comfort-height toilets, this model is a solid match.

Who will find the height comfortable?

You’ll likely be comfortable with this height if you prefer a traditional chair-like stance or if household members are shorter or younger. If you need easier sit-to-stand motion for mobility reasons, consider whether you prefer Universal/Comfort Height; otherwise this standard height works well for many users.

Seat design and coverage

You’ll notice the heated seat covers the full seating surface for consistent warmth. The elongated bowl gives you more room than a round bowl and tends to feel more comfortable during extended use.

Installation and compatibility

You’ll want to plan for a couple of practical installation steps. The WASHLET+ concealed connection keeps the look tidy, but you’ll still need a grounded GFCI outlet nearby for the bidet seat’s electrical functions. Standard toilet rough-in dimensions apply, but check your bathroom layout and plumbing before purchasing.

Power and plumbing requirements

You’ll need a standard 120V grounded outlet within reach of the seat’s cord; if you don’t have one, you’ll need an electrician to add an outlet. The water connection is standard for toilets, and the WASHLET+ is designed to fit this model with minimal visible hoses when installed as intended.

Difficulty and time needed

You’ll probably find the physical installation similar to other two-piece toilets, which most handy homeowners can handle, but adding the WASHLET+ and ensuring correct concealed connections may feel fiddly. If you want perfect fit and clean-looking hookups, hiring a plumber for the toilet and an electrician for the outlet is an efficient choice.

Cleaning and maintenance

You’ll spend less time scrubbing thanks to PREMIST and CEFIONTECT, but some routine cleaning will still be required. The PREMIST wets the bowl before use to help waste slide off, and the CEFIONTECT glaze discourages waste from sticking, which together reduce the frequency and intensity of manual cleaning.

What parts need regular attention?

You’ll want to wipe the exterior surfaces and the seat regularly, and occasionally clean under the rim where mineral buildup can occur. The wand self-cleans with EWATER+ technology, but you should still visually inspect it and wipe it down per the maintenance schedule in the manual.

Filters and replacements

You’ll benefit from the air deodorizer’s filter system, but filters do wear out over time and may need replacement depending on use. You’ll want to consult the TOTO manual or the product support site for recommended replacement intervals and OEM part numbers to ensure optimal deodorizing performance.

Energy use and water efficiency

You’ll be saving water with the 1.28 GPF rating versus older, higher-flow toilets. That reduction in water usage can lower your utility bill over time and may qualify you for local water-efficiency rebates depending on your jurisdiction. The bidet functions use some electricity for heating the seat, water, and dryer, but these features are generally energy-efficient by design.

How much energy does the WASHLET+ consume?

You’ll find that energy use is modest; the seat heater and water heating elements are designed for efficiency. If energy consumption is important to you, you can minimize usage by adjusting standby settings, using energy saver modes if available, or powering down during extended absence.

Water savings compared to older models

You’ll save a noticeable amount of water if you’re replacing a 1.6 GPF toilet or older. Over the long term, those savings add up, and reducing paper use thanks to the bidet can also be a small environmental and cost benefit.

Noise, privacy, and user experience

You’ll find normal bathroom sounds from flushing and the bidet operation, including the warm air dryer which produces a soft hum. The WASHLET+ models are tuned for everyday household noise levels; they don’t draw unnecessary attention but provide a reassuringly solid operational presence.

Is the dryer loud?

You’ll notice the warm air dryer, but it’s not loud enough to be intrusive in most bathroom layouts. If you’re particularly sensitive to noise, turning the dryer to a lower setting or using it briefly can give you the benefit without the full sound.

Odor control effectiveness

You’ll get a noticeable reduction in odors thanks to the air deodorizer and filters. It works best as part of a comprehensive bathroom approach — good ventilation plus the deodorizer keeps the room feeling fresher.

Pros and cons

You’ll want a balanced view before deciding. Below are objective strengths and potential drawbacks to help with your decision.

Pros

• You’ll enjoy strong bowl cleaning from the TORNADO FLUSH® combined with CEFIONTECT for minimal sticking.
• You’ll get a luxurious cleansing experience with adjustable warm water, oscillating/pulsating modes, and an automated self-cleaning wand.
• You’ll experience comfort and convenience from a heated SoftClose seat, warm air dryer, deodorizer, and night light.
• You’ll save water with a modern 1.28 GPF rating compared to older models.

Cons

• You’ll need a grounded electrical outlet near the toilet for bidet functions, which could add installation cost if you don’t have one.
• You’ll pay more up front than for a basic non-bidet toilet, so it’s an investment rather than a budget buy.
• You’ll still need occasional maintenance for filters, and some parts may require OEM replacements for best performance.

Who is this model best for?

You’ll find this model ideal if you like the idea of a high-performance flushing toilet paired with advanced bidet comfort. It suits a range of buyers: homeowners upgrading to a more hygienic, water-efficient toilet; families who want odor control and easy cleaning; those who appreciate heated seats and a dryer; and people who want a premium bathroom experience without fully integrated one-piece systems.

Is it good for seniors or those with mobility challenges?

You’ll appreciate features like the warm seat, gentle cleansing, and dryer which can help with personal hygiene for those with limited mobility. If reaching a lower seat height is important, confirm that the standard height works for the individual; some may prefer comfort-height for stand-to-sit ease.

Is it right for small bathrooms?

You’ll likely be fine with the elongated bowl if your bathroom has adequate length; measure your space first. The two-piece design can fit smaller bathrooms better than some one-piece or integrated combos, but you must ensure the elongated shape clears other fixtures.

Comparison to other options

You’ll compare this combo favorably with basic toilets and many aftermarket bidet seats. Against fully integrated bidet-toilet combos, this two-piece plus WASHLET+ seat gives you modularity: if you need to replace the seat later, you can without swapping the entire toilet. Versus cheap add-on bidet seats, the S5 provides more advanced wash modes, better hygiene features like EWATER+, and a more refined experience.

How it stacks up on hygiene and tech

You’ll find the EWATER+ wand cleaning and PREMIST system give this model an edge over basic add-on seats that lack automated wand sanitization or bowl pre-misting. The combination of TOTO’s flushing tech and bidet hygiene features is a comprehensive approach not always matched by competitors.

Cost-effectiveness

You’ll pay more initially but gain long-term benefits: less paper use, water savings, and potentially fewer deep-clean sessions. If you value hygiene and comfort, the upfront cost is balanced by convenience and utility savings over time.

Tips for buying and installation

You’ll make the process smoother if you measure your rough-in and bowl clearance before ordering. Confirm the outlet location or plan to add one, and consider hiring professionals for plumbing and electrical work to achieve the cleanest install.

What to check before purchase

You’ll want to confirm rough-in dimension, available power outlet proximity, and whether the elongated bowl fits your space. Also check local codes if you plan to benefit from water-conservation rebates or need to meet specific plumbing standards.

Installation advice

You’ll get the best result with careful sealing of the bowl-to-floor connection and secure tank mounting, then proper electrical hookup for the bidet seat. If you’re not experienced, paying for a plumber and an electrician saves time and prevents common mistakes that could cause leaks or improper function.

Maintenance schedule and long-term care

You’ll extend the life of this toilet by following a simple maintenance plan: clean the bowl and exterior weekly or biweekly depending on use, inspect and replace deodorizer filters as recommended, and check the wand and spray nozzles periodically. Keep the manual handy for any troubleshooting and replace consumables with OEM parts for the most reliable fit.

Seasonal and occasional checks

You’ll want to winterize if your home is vacant in freezing weather — consult the manual for specific steps. Occasionally check for mineral build-up in your area’s hard water conditions and use manufacturer-approved cleaners to avoid damaging the glaze or electronic components.

Troubleshooting basics

You’ll reset the seat electronics by unplugging and plugging back in if you experience minor glitches, and consult the user manual or TOTO support for persistent issues. For leaks or flush performance problems, check the tank fittings and seal integrity, and call a plumber if you’re unsure.

Frequently asked questions

You’ll probably have some specific concerns if this is your first bidet-toilet combo; here are clear answers to typical questions.

• Will the bidet seat fit this Drake bowl?
  You’ll find this model is packaged to match, and WASHLET+ seats are designed for compatibility with the corresponding TOTO bowl models. Double-check the product documentation to confirm fit.

• Do you need a special electrical outlet?
  You’ll need a grounded 120V outlet, ideally on a GFCI circuit if the bathroom requires it. An electrician can install one if you don’t have it.

• How often do filters need changing?
  You’ll replace deodorizer filters based on usage and manufacturer recommendations; heavy-use homes may change them more often. Check the manual for part numbers and intervals.

• Is the PREMIST always on?
  You’ll be able to control PREMIST settings; consult the seat’s control options to enable or disable pre-misting as desired.

• Can the S5 seat be used without power?
  You’ll still have a functioning toilet for flushing, but bidet-specific features like heated water, dryer, and seat heating require power.
