Bathroom Remodel Toilet Installation in San Marcos, CA
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 correctly. 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.

Smart Toilet and Bidet Installation in San Marcos
Smart toilets and bidet seats from TOTO Washlet, Kohler and Bio Bidet need a water connection and typically a nearby GFCI outlet.

We also explain basic maintenance like cleaning the nozzle and filter.
Customer-Supplied Toilet Installation in San Marcos, CA
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.

Comfort-Height and ADA Toilet Installation in San Marcos
Comfort-height toilets put the seat at about 17 to 19 inches, which is easier on knees and backs.
