Why the TOTO Washlet S5 Is Becoming a Top Choice for Canadian Homes

Bidet seats have become one of the most requested upgrades in modern bathrooms, and the TOTO Washlet S5 stands out for its comfort, hygiene, and thoughtful design. Whether you’re renovating a bathroom or looking for a simple upgrade without replacing your toilet, the S5 offers features that make daily routines cleaner and easier. It sits in the middle of our range of TOTO Washlet bidet seats.

The S5 comes in both elongated (SW3446#01) and round (SW3445#01) options, so it fits most toilets already installed in Canadian homes.

If you are weighing it against the entry-level seat, see S5 vs S2. If you are replacing an older C5, see C5 vs S5.

1. A Clean You Can Actually Feel

Many people switch to a bidet seat because they want a better clean than toilet paper can provide. The S5 uses a warm water wash that starts instantly and stays warm the entire time. You can choose between oscillating or pulsating spray modes, and adjust the pressure and position to match what feels right for you.

It’s simple, effective, and far more comfortable than a cold-water spray.

2. Small Comforts That Make a Big Difference

The S5 includes everyday comforts that quickly become hard to live without:

Heated seat

The temperature stays consistent across the entire seat surface.

Warm air drying

Helps you dry off comfortably without rushing.

Built-in night light

Soft light inside the bowl guides you during late-night trips.

Air deodorizer

Filters air from the bowl to reduce bathroom odors.

These features work quietly in the background but noticeably improve day-to-day use. Our guide to the eight must-know WASHLET features covers each of them in more detail.

3. Hygiene Features That Set It Apart

TOTO focuses heavily on cleanliness, and the S5 includes several systems that support this:

PREMIST lightly coats the bowl before use so waste sticks less.

EWATER+ rinses the wand automatically inside and out.

CLEAN RESIN keeps the wand and seat surface easier to maintain.

These features reduce buildup and help keep the toilet area fresher between cleanings.

4. Easy Controls and Personalized Settings

The S5 is operated with a slim wireless remote rather than a panel attached to the seat, which is part of why the seat itself looks so clean in place. The remote can be wall-mounted beside the toilet and gives quick access to spray position and pressure, water temperature, dryer level and every other function.

There are also four memory settings, which is useful for families or shared bathrooms. Each person can store their preferred spray position and temperature without needing to readjust every time.

If you would rather have the controls attached to the seat, that is the S2 — it uses a side arm panel instead of a remote.

Fits Most Existing Toilets

One of the benefits of choosing a Washlet is that you don’t need a full toilet replacement. The S5 is designed to fit most standard elongated and round toilets, making it an easy upgrade for homeowners who want better cleanliness without a full renovation.

It does need a grounded electrical outlet within reach of the toilet, which most Canadian bathrooms do not have behind the bowl — worth booking an electrician before the delivery date. That and the other ordering traps are covered in the pros and cons of TOTO toilets.

Is the TOTO S5 Worth It?

For anyone wanting a cleaner, more comfortable bathroom experience, the S5 is one of TOTO’s best mid-high level Washlets. It offers many of the brand’s top features without the premium price of the S7. The instant warm water, deodorizer, heated seat, and self-cleaning systems make it a practical choice for long-term use.

If you’re upgrading your bathroom, the S5 brings noticeable improvements in comfort and hygiene with very little installation effort.
