Troubleshooting and fixing leaks on your aquabliss TheraSpa (HS300)
The TheraSpa shower set uses rubber washers at each connection point to create a watertight seal. Most leaks after installation are caused by a washer that is missing, damaged, or not seated correctly — all of which are quick and straightforward to fix.
How to check and fix a washer issue
Start by identifying which connection is leaking. Unscrew that connection and look inside — the washer should be visible, sitting STRAIGHT and FLAT against the inner surface. If it has shifted or has an edge that's curled up, use your fingers or a screwdriver to press it back into place. Reattach the connection and run the water to test.
If the leak continues: remove the washer completely using a screwdriver, flip it over so the other face is forward, reseat it flat, and reattach. A washer that has been compressed on one side often seals better when flipped.
For a small persistent drip: wrap 3–4 layers of plumber's tape around the threads before reattaching. This fills microscopic gaps and usually resolves any remaining leak.
A leak from the back of the shower mount
If water is leaking from behind the shower mount bracket rather than from a hose or head connection, the issue is most likely with the split washer inside the mount itself — not a connection point. Please see our dedicated Shower Mount Leaking guide for step-by-step instructions on reseating this washer correctly.
