How We Repair Your Kohler Tankless Toilet

Can you repair my tankless toilet today?

Is the repair guaranteed?
Yes. Parts and labor are covered by our 90-day warranty. If the same problem comes back within that time, we return and fix it.
Do you work on all Kohler models?
We repair current and older Kohler models. Some discontinued parts can be hard to find; if that is the case for your model, we tell you before you pay for a repair.
Should I repair or replace my tankless toilet?
A tankless toilet typically lasts about 7 to 15 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
