Can't Find Your Part?
We'll Custom Fabricate It.
Discontinued model. Obsolete brand. Part that simply doesn't exist anymore. No problem. We custom machine replacement parts for virtually any plumbing fixture — so you don't have to rip out your shower wall, retile, or gut a bath you love.
Just send us the old part. We use it as the master to machine an exact duplicate — same dimensions, same fit, same function. No guesswork, no measurements required on your end.

Luxury plumbing fixtures, made repairable
The Plumbing Part Doctor helps homeowners, plumbers, contractors, designers, property managers and maintenance teams identify and source replacement parts for luxury plumbing fixtures. From cartridges and valve components to hard-to-find parts, we help keep existing fixtures in service instead of replacing the entire system.
What we specialize in
We specialize in thermostatic cartridges, pressure-balance cartridges, diverter cartridges, volume-control cartridges, service stops, check stops, ceramic cartridges, hot and cold cartridges, and internal valve components for high-end shower, tub and faucet systems.
Can’t find the replacement?
If the original part is discontinued or no longer available, we may be able to source an alternative or custom fabricate a replacement using your existing part as the master.
Help before you order
Not sure which part you need? Send us the brand name, model or part number, clear photos of the existing part and a description of the issue. We’ll help confirm the correct part or replacement option before you order.
