Step by step
- Disconnect hose. Shut off and disconnect the garden hose.
- Drain. Open all valves and the drain plug; tilt the column if needed.
- Open valves. Leave valves half-open so trapped water can expand.
- Store or cover. Bring portable columns indoors or cover them.
- Spring. Inspect seals and flush before first use.
When to winterize
Drain before the first hard freeze forecast in your area. Even one night below freezing can crack a full plastic tank or brass valve.
Solar shower columns
Solar showers like VEVOR's store several gallons in the column itself. Disconnect the hose, open all taps (shower and foot tap), and use the drain plug if there is one. Tilt the column to empty any remaining water. Storing the unit indoors is the safest option.
Plumbed outdoor showers
Shut off the supply from inside the house, then open the outdoor valves and drain. Many homeowners install a frost-free valve or a drain-down valve so lines empty automatically.
Spring start-up
- Check seals and hose washers for cracks.
- Flush the tank with clean water before the first use.
- Test temperature carefully on the first sunny day; stored water can be very hot.

Frequently asked questions
Can I leave a solar shower out in winter?
Only if fully drained; storing indoors is safest.
At what temperature should I drain my outdoor shower?
Drain it before temperatures are forecast to drop below freezing, 32°F, even for one night.
Do I need antifreeze?
For drained solar columns, no. For plumbed outdoor showers with traps, some people add RV antifreeze to traps; never use automotive antifreeze.
Can I leave the hose connected?
No. Disconnect and drain the hose; water trapped in the hose and hose bib can freeze and crack them.
How do I store a solar shower column?
Drained and dry, indoors or under a cover, lying flat or upright where it can't fall over.
