Whether you're replacing an old, inefficient toilet or installing a new one during a bathroom remodel, our team handles standard toilet installations with care.

Bathroom Remodel Toilet Installation in Costa Mesa, 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 properly. If you are moving the toilet, we can relocate the drain, which on a slab foundation requires cutting and patching concrete. We plan timing so the toilet goes in after tile and grout have cured.
Low-Flow WaterSense Toilet Installation in Costa Mesa, CA
Modern WaterSense toilets use 1.28 gallons per flush or less, and dual-flush models offer an even lighter option for liquid waste. Swapping an old 3.5 gallon toilet makes a noticeable difference on your water bill. Some local water providers have offered rebates for high-efficiency toilets, so it is worth checking with yours. We help you choose a model with a high MaP flush rating.

Wall-mounted toilets offer a modern look and can free up floor space, but their installation is more complex, involving in-wall carriers and concealed tanks.
