Question 1: What are the Differences Between a WASHLET and a WASHLET+?

First, let’s go over the differences between these two products. Purchase a WASHLET and you’ll get an elegant, feature-packed bidet seat that you can install atop your existing toilet. Opt for a WASHLET+ and you’ll get both a toilet and a bidet seat that fit seamlessly together so that the bidet seat’s water and electrical connections are hidden from view. TOTO’s WASHLET+ systems feature a wide range of toilet and bidet seat combinations (we currently offer over 70 WASHLET+ systems), so it’s easy to find one that meets both your aesthetic and performance preferences.

Question 2: Will a Regular WASHLET Fit on a WASHLET+ Toilet and Vice Versa?

You might have noticed that the model numbers of TOTO’s WASHLET bidet seats are the same as their WASHLET+ bidet seats. However, while they function the same, they are not interchangeable!

For example, the S500e WASHLET has the same silhouette and bidet functions as the S500e WASHLET+, but the two seats are physically configured a bit differently. While this design difference allows a WASHLET+ bidet seat to fit on a WASHLET+ toilet in such a way that its cord and hose are hidden, it also means that a WASHLET+ bidet seat can only be installed on a compatible WASHLET+ toilet.

In other words, while you can always remove a WASHLET+ bidet seat from a WASHLET+ toilet and install a regular toilet seat in its place, you cannot transfer a WASHLET+ to a toilet other than the one it came with (unless that toilet happens to be a compatible WASHLET+ model). Do note that you can always install a non-WASHLET+ bidet seat on a WASHLET+ toilet, but the cords and hoses will remain visible.

In comparison, a standard TOTO WASHLET will fit on most one- or two-piece toilets (excluding French curve toilets) so long as the bowl shape matches the bidet seat’s shape. In other words, an elongated WASHLET will fit on most elongated toilets, and a round WASHLET will fit on most round toilets, but a round WASHLET won’t fit on an elongated toilet and vice versa.

Question 3: What are the Pros and Cons of a WASHLET vs. a WASHLET+?

Here are a few questions to consider when trying to decide between a TOTO WASHLET or a WASHLET+:

  • What’s my budget?
  • Am I content with my current toilet or would I like to upgrade?
  • Is auto-flushing a must-have feature for me?
  • How important is a sleek silhouette?

 The TOTO WASHLETS we sell range in price from $350-$1350, whereas WASHLET+ systems are pricier, coming in between $850-$3050. Of course, the price difference is due to the fact that WASHLET+ systems come with both a toilet and a bidet seat, so you’re getting a lot of bang for your buck, especially at the lower end of the WASHLET+ price spectrum. However, if you’re working on a tight budget, you may find that price alone is the deciding factor in whether you purchase a solo WASHLET or an entire WASHLET+ toilet and bidet system.

TOTO toilets are stylish, efficient and powerful, so if you’re unhappy with your existing toilet, you may want to consider upgrading to a new fixture via a WASHLET+ system. There are tons of WASHLET+ systems to choose from, with a wide range of silhouettes, flush volumes, heights, and rough-ins, so it’s likely you’ll be able to find one that suits you well.

Third, consider whether you want auto-flush capabilities. Currently, no solo bidet seats offer auto-flushing, as this capability requires specific toilet configurations. If auto-flushing is a must-have, you’ll want to seriously consider either a WASHLET+ System or an integrated unit, as many of these units offer this unique feature. When it comes to WASHLET+ systems, toilets paired with the S550e and S500e WASHLET+ offer the auto-flush upgrade.

Aesthetic preference is the fourth and final consideration you’ll want to weigh when deciding between a WASHLET or a WASHLET+ system. While all TOTO’s bidet seats have a sophisticated look, some customers want their bidet seat to look as much like a regular toilet seat as possible. Because WASHLET+ toilets conceal the bidet seat’s cords and hoses, WASHLET+ systems offer a sleek look that’s unblemished by unsightly cords and hoses protruding from the side of the seat.

Final Thoughts

If you’re looking to add bidet cleansing to your existing toilet, and you’re ok with visible cords & hoses as well as flushing the toilet manually, a regular WASHLET may be the right choice for you. On the other hand, if you’re wanting to replace your existing toilet, prefer a silhouette that’s unbroken by clunky cords or hoses, and/or want a toilet that flushes on its own when you stand up, a WASHLET+ System is probably the better fit.
