Kohler faucet and shower part identification
A model-first guide to Kohler faucet valves, Rite-Temp shower systems, and service-part generations.
Direct answer
Locate the Kohler model or valve platform, use its service-parts diagram, and verify the complete cartridge or valve number against the removed component.
Fit facts
What identifies this match
Use these details together. One matching feature does not establish compatibility.
- Model clue
- Kohler model identifiers commonly begin with K- on product documentation
- Service clue
- Replacement parts may use GP-prefixed kit numbers
- Shower family
- Rite-Temp is Kohler's pressure-balancing shower-valve platform
- Valve distinction
- Thermostatic, pressure-balancing, and volume-control systems require different service paths
- Generation risk
- A current service kit may supersede an older component, but only an official listing establishes that relationship
- Best confirmation
- Model-specific service diagram plus physical comparison
Locate the K-number
Search the installation guide, invoice, product page, and any label beneath the sink. Keep the full K-number and suffix together so Kohler's support materials can distinguish configuration and finish.
Read service-kit numbers
Kohler service kits frequently use a GP prefix. Do not remove that prefix or assume that two kits with nearby numbers are revisions of one another; verify the exact number in the model's parts diagram.
Identify the shower platform
Rite-Temp pressure-balancing valves, thermostatic valves, and separate volume controls perform different jobs. Note whether one control sets both flow and temperature or whether the installation has dedicated controls.
Handle generations deliberately
Valve bodies and service assemblies can change while visible trim remains stylistically similar. Follow any Kohler supersession statement and compare the existing stem, mounting pattern, and valve features before accepting a newer kit.
Keep fixture context attached
A kitchen faucet valve kit, widespread lavatory valve, roman-tub assembly, and in-wall shower component are not interchangeable categories. Use handle count and installation location to constrain the search.
Decision path
Find the K-number, open Kohler's parts resources, and record the exact GP or service number shown. Compare the removed assembly and installation details, then resolve any supersession through current Kohler documentation before purchase.

Questions
Before you remove or replace the part
What is a Kohler K-number?
It is the model identifier used in Kohler product documentation; retain its suffix when searching.
Does a GP number prove fit?
Only when the complete number is listed for the specific product or officially identified as its replacement.
Can new trim identify an old valve?
Not by appearance alone. Confirm the valve platform and generation behind the wall.
