Product Technologies / Benefits:

  • SanaGloss Ceramic Glaze: This innovation, which Toto has trademarked to almost all of their sinks, provides a solution to build-up on the surface of the sink. SanaGloss seals the porcelain surface with an ionized barrier, creating a super-smooth surface that prevents particles from adhering to ceramic; meanwhile a catalyzed ion barrier actually repels particles away, keeping the toilet looking clean and new for years to come. Whether it is used in a commercial or residential application, SanaGloss will make sink maintenance a breeze.

Toto LT540G Reviews

Rated 5 out of 5 by from Quality bathroom sink We bought 3 of these sinks; 2 for the master bathroom and one for the guest bathroom. I am very pleased with the color, finish, shape and size. The Sedona beige is a nice change from stark white. It is easy to fill, quick to drain, and doesn't require any maintenance. It has the sleek, contemporary look we wanted. I would definitely recommend to a friend.

Rated 5 out of 5 by from Great sink! I wanted a larger than normal sink for the master bath and one that was large enough to wash my hair in without splashing out. I already had the smaller version of this sink in two bathrooms and was very happy with the Sanagloss finish and Toto quality. This sink is perfect and not too large, but make sure your faucet will fit in the counter depth you have.

  • How deep is the bowl?

    A. The Toto LT540G has a basin depth of 7.875".
  • Can you give me the rough in cut-out dimentions?

    A. The Cut Out Dimensions for the Toto LT540G Undermount Sink are 21 1/4" W x 14 3/8" D.
  • What other parts will I need?

    A. The Toto LT540G does not come with the drain assembly, as this is usually provided with whichever faucet you order. Other than that it includes everything needed to install.
  • Will this sink mount well in a 30" vanity? Is there a smaller width model?

    A. The Toto LT540G can be mounted into a 30" vanity & based upon the spec sheet I think it would fit there nicely. If you wanted a smaller one I would recommend the LT191G.
  • What p-trap and tubing outlet goes with this sink?

    A. The Toto LT540G is not particular to any type of P-trap. Any P-Trap that is fitting to your space and aesthetic requirements will be fine. P-Traps are very common. The Kohler K-8998 would be an appropriate choice.
  • is there an overflow on this sink?

    A. This sink does not have an overflow.
  • My vanity is 21 inches from back to front. Will this sink fit or should I order the LT542G? The vanity is 9.5 feet long.

    A. The Toto LT540G is an undermount sink with an inner length measurement of 14 3/8". Either of these sinks would fit your needs.

  • Is there an overflow on this sink?
