For private saunas
Booked and paid online 24/7, without phone calls
A private sauna is rented out per time slot to one group at a time. With SpaSlot your guests book on your website themselves: they pick a date, a time slot, the number of guests and their package, and pay straight away with iDEAL.
We set up the system around how your sauna works: fixed time slots or half-day sessions, overnight slots, cleaning time between bookings, a deposit or full payment upfront and your house rules in the confirmation.

What a private sauna needs
Time slots, half days and nights
Rent out per 2 or 2.5 hours, per half day or with an overnight slot. With a morning offer or early-bird for quiet hours and a price per weekday, Friday or weekend.
Packages and extras
Sell a prosecco package, bathrobes, breakfast or birthday decorations right at booking. Extra guests above your base price are calculated automatically.
Paid when booked
Your guest pays straight away, in full or with a deposit. Unpaid bookings expire automatically, so your slot becomes available again.
How your guest books
From website to sauna, in five steps

Starting a private sauna?
Get your bookings right from day one
If you are opening a private sauna or wellness, you want to be bookable online from the day you open. Go through these points beforehand; we help you with each of them.
Time slots and prices
How long is a session, how much cleaning time do you need, and does your price differ per day or time of day?
Payment and cancellation
Do guests pay in full upfront or do you use a deposit? Until when can a guest cancel free of charge?
House rules
Minimum number of guests, children, swimwear: put it in the confirmation so your guest knows in advance.
Packages
Which extras do you sell? A package at booking increases the value of each visit.

The people behind SpaSlot
Software from people you can simply call
SpaSlot is based in Rotterdam. We have been building software since 2018 and developed SpaSlot together with private saunas that use it every day.
We know what sauna guests ask: can we arrive later, can someone join, are bathrobes included? That is why as many answers as possible are already in the booking and the confirmation.
