Accessories

Add-ons, covers, steps and filters to complete your ThermoX setup.

Covers

An insulated cover significantly reduces energy consumption by preventing heat loss overnight and between sessions. We recommend using a cover whenever the unit is not in use. Compatible covers are available for the Core, Pro and Elite — specify your model when ordering.

Steps and entry aids

A non-slip entry step makes getting in and out of your plunge safer and more comfortable, particularly for the Pro and Elite models. Steps sit flush against the tub exterior and fold flat for storage.

Filter cartridges

Replacement 20 micron filter cartridges for the Core and Pro. Replace every 3 months under regular use, or sooner if water quality deteriorates. The Elite uses a dual-stage filter — specify your model when ordering.

Skimmers and cleaning tools

A surface skimmer keeps debris and biofilm off the water surface between sessions. Compatible with all ThermoX tub models. Also available: interior tub cleaning brushes and chemical test strips for water quality monitoring.

Water treatment kits

Our recommended water treatment starter kit includes non-foaming chlorine granules, pH balancer, alkalinity buffer and a 3-month supply of test strips. Keeps your water clean, clear and balanced between full water changes.
