A running, leaking or rocking toilet is more than annoying it can waste hundreds of gallons of water a month and quietly rot the subfloor underneath. Obsta Plumbing has been repairing and installing toilets in Katy and Houston homes for over 15 years, and most repairs are finished in a single visit with parts already on the truck.
We fix every kind of toilet problem: running tanks, weak flushes, ghost flushing, wax-ring leaks, broken flanges, rocking bowls and chronic clogs. When repair isn't worth it, we install high-efficiency 1.28 gpf and dual-flush toilets from Toto, Kohler and American Standard that look better, flush stronger and cut your water bill.
Every install includes a new wax ring or waxless seal, new supply line, new shutoff valve when needed, and a clean haul-away of the old unit. We protect your floors, leave the bathroom cleaner than we found it, and stand behind every job with our workmanship warranty.

Frequently asked questions
How much does it cost to fix a running toilet?+
Most running-toilet repairs in Katy run $150-$300 depending on whether the fill valve, flapper, flush valve or supply line needs replacing. We quote the repair upfront before starting.
How much to install a new toilet in Katy, TX?+
Standard toilet installation typically runs $250-$450 in labor (new wax ring, supply line, shutoff if needed, haul-away of the old toilet), plus the cost of the toilet itself. Premium installs (wall-hung, smart toilet, bidet wiring) are quoted individually.
Why does my toilet keep clogging?+
Repeated clogs in the same toilet usually mean one of three things: a partial blockage in the trap or drain line, an under-powered low-flow toilet that needs replacement, or a venting issue. We can camera the line to identify the cause and recommend the right fix.
Should I repair or replace my toilet?+
If your toilet is under 10 years old and the issue is a single component (fill valve, flapper, wax ring), repair is usually the right call. If it's 15+ years old, uses 3.5 gpf or more, or has a cracked tank or bowl, replacement with a modern 1.28 gpf model will pay for itself in water savings.
