Toto MS853113S Reviews

Rated 4 out of 5 by from much improved I ordered to of these Toto's in place of some strange toilets the builder put in when he first built our place 8 years ago. They have been in for three weeks now, and I have not had to plunger opposed to the others that I was plunging every few days (2, 8 year old boys and a wife :) ). Esthetically, they are quite nice. Their one piece design makes for easy clean up (see above, 2, 8 year old boys!), and the included seats are a nice bonus. The other toilet I have is an American Standard Champion. With the upgraded flush valve, it also works quite well, although there first generation was not so reliable. It also seems to need to be much bigger due to the design of its 4 inch trapway. The Totos take up much less space. The one element that I'm not so sure about is the tank lid, which actually just rests on top of the tank and is held in place with a velcro strip. This contributes to the perception that it is smaller, but I'm more used to the bigger lids which fit over and around the tank...also, the lid slopes so its not a great place to store anything.

Rated 5 out of 5 by from Great toilet Once you flush the toilet the water returns immediately and the seat closes just by touching it gently. I own two of these toilets!

Rated 5 out of 5 by from Excellent low-flush toilet Highly recommended. Nicely designed (looks small in bathroom compared to your old toilet) in one piece, which gives great stability. Low-flush (1.6 gallons per flush) saves a lot of water ? only a few times have we had to flush twice to get the job done. Easy to keep clean. The self-closing seat is ok but not as good as the seat on an earlier Toto purchase 2 or 3 years ago. Don't know why.

Rated 2 out of 5 by from Flush Value Mechanism Poorly Constructed I've purchased several of these toilets and all of them develop leaky flush value mechanisms within months. This must be due to a major design flaw or cheap components or planned obsolesce.... The toilet works well overall, but expect future headaches...

Rated 5 out of 5 by from Great Product The Ultramax was easy to install and the finish is beautiful. The 3" flush valve easily handles a large amount of waste. No backup problems to date. I was hesitant about the product being shipped such a long distance. However the Toilet and Sink that I ordered both arrived in great condition thanks to a great packaging job and individually delivered on a pallet.

Rated 5 out of 5 by from toto toilet is best out there Loved this toto toilet so much after we had it --- we replaced a Kohler toilet with another toto toilet. It flushes good & is quiet.

  • what is the length of round toilet? Is it 26 1/2?

    A. The Toto MS853113S has a length of 26-1/2".
  • Does this Toto have a standard bowl height or does it have the newly popular comfort height?

    A. The bowl height is 14.63 inches. It is not the comfort height.
  • May I find out the depth of this Toto toilet? The elongated toilets give depth measurements but not the round. Thank you!

    A. The Toto MS853113S should have the same bowl depth as it's elongated sister commode.
  • do you have any max flush commodes that are taller than the standard height?

    A. The UltraMax collection tallest seat height is 16.5"
  • I'm looking at the color: if I'm looking for a plain white toilet, should I be looking at the "colonial white" or the "cotton" color?

    A. The Toto MS853113S cotton is the closest to the true white finish.
  • Which of the Toto flushing options is the quietest and yet still provides a good flush?

    A. The E-Max flushing system is the least noisey while giving a solid flush.
  • Can I order a brushed nickel trip lever for this toilet? If so what is the #of the part?

    A. The Toto MS853113S brushed nickel trip lever would be the THU004.
