Home Spa: How to Build a Spa Bathroom at Home
By Claire Whitmore. Updated October 2026.
A home spa doesn’t require a renovation. Most people get 80 percent of the feeling from three things: a great shower, thick towels and a robe, and a little heat or cold. The rest is a matter of budget and space. This page collects every LifetimeLuxury guide on the subject in one place, in the order we’d tackle them.
Start here: the five-step home spa
- Upgrade the shower. A rain head or a good handheld changes the daily routine more than anything else. See our shower head picks.
- Buy proper towels and a robe. Heavy cotton terry, washed without fabric softener. Towels and robes.
- Control the light and scent. Dimmable warm lighting and one good candle or diffuser. Diptyque Baies is a classic.
- Add heat. An infrared sauna fits in a corner and usually runs on a standard household outlet for smaller units, but check the specs, since larger models need a dedicated circuit. Infrared sauna guide.
- Add cold, if you’re into it. A cold plunge tub pairs with a sauna for contrast therapy. Talk to a doctor first if you have heart conditions. Cold plunge guide.
Home spa budget tiers
| Budget | What it buys |
|---|---|
| Under $500 | Shower head, towel set, robe, candle |
| $500 to $5,000 | Add a one- or two-person infrared sauna or a portable cold plunge |
| $5,000 and up | Traditional sauna, chilled plunge with filtration, soaking tub, steam shower |
Budget ranges are our estimates based on typical retail prices in 2026, not quotes.
