Never run the heater dry
The heater is switched off before draining and stays off until the tub reads full. If the water ever drops while it's on, power is cut instantly.
Hot tub drain & fill controller
Fresh water, without the chore.
Spa Timer drains your hot tub, refills it and switches the heater back on — by itself, safely, while you do anything else. One tap on your phone starts it.
Peace of mind, built in
A controller that watches the water, so you don't have to.
Never overflow
A float sensor stops the fill the moment the tub is full, with a timer as a backstop. No more hose left running into the yard.
Fresh water from your phone
Start a full drain-and-fill with one tap, watch every step live, and get an email if anything needs you.
How it works
A small controller sits beside your tub's power and plumbing. It does the work; the app keeps you in the loop.
We install it
Spa Timer connects to your heater power, a drain pump and your fill valve, plus a float that knows when the tub is full.
You tap Start
From anywhere. Or press the button on the controller. You can stop it at any time from either.
It handles the rest
Power off, drain, settle, refill, settle, heater back on — each step checked by the sensors.
Power off→Drain→Settle→Fill→Settle→Power on
