Smart Toilet and Bidet Installation in Middletown
Smart toilets and bidet seats from TOTO Washlet, Kohler and Bio Bidet need a water connection and typically a nearby GFCI outlet. We install the T-valve or dedicated supply, mount the seat and test spray, heat and dryer functions. If an outlet is needed, we coordinate with a licensed electrician. We also explain basic maintenance like cleaning the nozzle and filter.

Wall-Hung Toilet Installation in Middletown, DE
Wall-hung toilets mount to a steel carrier inside the wall, with the tank hidden behind an access plate. They free up floor space and make cleaning simple, but they need a wall at least 2 by 6 deep or a furred-out chase. We install Geberit, Grohe and Kohler carrier systems and set the bowl height to your preference. This work is easiest during a remodel when the wall is open.

Low-Flow WaterSense Toilet Installation in Middletown, DE

We help you choose a model with a high MaP flush rating.
ADA-Compliant Toilet Installation in Middletown
For accessibility needs, we offer expert installation of ADA-compliant toilets, which are typically taller and easier to use for people with mobility challenges.
