Bathroom Remodel Toilet Installation in O'Fallon, MO
Remodels often raise the floor with new tile, which can leave the old flange too low. We use flange extenders or replace the flange so the seal compresses properly. If you are moving the toilet, we can relocate the drain, which on a slab foundation requires cutting and patching concrete. We coordinate timing so the toilet goes in after tile and grout have cured.

Customer-Supplied Toilet Installation in O'Fallon, MO
If you already bought a toilet from a home center, we can install it for a flat labor rate. Before we arrive, we suggest checking that the rough-in on the box matches your bathroom. We inspect the fixture for shipping cracks before setting it, since damaged porcelain should go back to the store. We bring the seal, bolts and supply line so you do not have to.
ADA-Compliant Toilet Installation in O'Fallon
For accessibility needs, we offer professional installation of ADA-compliant toilets, which are typically taller and easier to use for people with mobility challenges.

Smart Toilet and Bidet Installation in O'Fallon

We also explain basic maintenance like cleaning the nozzle and filter.
New Construction Toilet Installation in O'Fallon
In new homes and additions, we set toilets after the finished floor is in so the flange sits at the right height.

We flush-test and check for leaks before final inspection.
