The operating system for bathhouses.
Booking, front desk, POS, scheduling, waivers, and AI — built for shared sauna rooms, not stylist chairs. Starting at $89/month.
Your booking system can't see the empty seats.
Generic salon software treats every booking as one person in one time slot. But a sauna room with 8 seats can have three parties in it at the same time. Your system says "full" when there are 3 empty seats — and you turn away a walk-in who could have sat right down.
No capacity model
Boulevard, Fresha, Mangomint — all built for 1:1 appointments. None can model an 8-seat sauna with overlapping parties.
Five tools, five logins
Booking here, scheduling there, waivers on paper, POS on a separate tablet. Nobody has the full picture. Reconciliation eats your evenings.
Walk-ins turned away
One turned-away walk-in per week is $160–320/month in lost revenue. Your free tools are costing you money you can't see.
The occupancy engine.
Tonttu models how bathhouses actually work. A shared sauna room with capacity 8 can have three overlapping parties — 2, 3, and 2 people — using 7 of 8 seats. The system shows one seat available. A walk-in arrives. They fit. No competitor in the independent price range does this.
Variable party sizes. Turn times between sessions. Private rooms. Real-time grid-based availability for online booking. All in one engine.
One system, not five.
Most bathhouses run on 4–5 disconnected tools. Tonttu replaces all of them — and adds capabilities none of them offer. See the savings.
Everything the house needs.
Shared-room booking engine
Online booking with real-time availability. Party sizes, turn times, grid-based display. The hero feature.
Front desk kanban
Bookings move through their lifecycle: confirmed → arrived → in service → completed. Walk-ins slot in if capacity allows.
POS + gift cards + store credit
Cash, card, gift cards, and store credit as direct tender. Register reconciliation built in. One system, not three.
Customer CRM with "their usual"
Booking history, preferences, tags, notes, accommodations. When a regular calls and says "the usual," your staff knows exactly what that means.
Staff scheduling + mobile app
Build the week, publish it, staff see it on their phone. Shift swaps, open shifts, claim requests — all in the same database.
Digital waivers
Built into check-in. Signed waivers sync to the customer CRM automatically. No more paper. No more separate tool.
Analytics dashboard
Bookings trends, room utilization, peak hours, sales summary, staff performance. Real-time, owner-only.
Tonttu AI assistant
An in-app assistant that reads live data and proposes actions. No competitor has this. See below.
Tonttu tends the house.
Tonttu is a built-in AI assistant — not a chatbot glued on top, but wired into the actual business data with strict safety boundaries. He reads the room, answers questions, and proposes actions. He never acts alone.
"Who's arriving next?"
→ "The Henderson party, 2 people, 3:30 PM, Shared Sauna A.""How busy were we today?"
→ "14 bookings, 78% utilization, 3 walk-ins. Peak at 4 PM.""Is the sauna available at 4 PM for 2?"
→ Proposes a booking. Staff clicks Confirm. HMAC-signed, 5-min expiry.Propose-and-confirm. HMAC-signed tokens. Tenant-scoped reads. No direct database access. He can suggest, but he can't act without you saying yes.
Under $90/month. All-in.
Less than half of Boulevard. No per-user pricing. Scales from one location to a franchise without re-platforming.
Most franchises replace 4–5 tools when they switch. See how much you'll save →
Quiet software for a quiet craft.
Paper textures. Caslon serif typography. IBM Plex Mono for data. A pixel-art Tonttu mascot. The grain overlay on every surface. This is not another neon SaaS dashboard — it is software that respects the bathhouse aesthetic.
