What does the CAPEX tab show in a Float Therapy Center model?
Use lender debt for the buildout, then fill the gap with investor or owner equity. For a Float Therapy Center, funders will want the startup-cost assumptions, $497k CAPEX, $312k minimum cash, lease terms, buildout quotes, tank count, payroll, and a runway to Month 13 breakeven. Here’s the quick math: the base case shows a 38-month payback and a 0.04% IRR, so the visit ramp and membership mix have to carry the deal.

Float Therapy Center Core Five Startup Costs
Float Tank Systems Startup Expense
Tank System Cost
$160k covers 8 float tank systems over Months 1-3, or about $20k per tank before build-out. That needs to include commercial tank hardware, filtration, controls, water circulation, and heating links. For installed readiness, add $30k for specialized water treatment and heating plus $150k for facility build-out and plumbing.
Room Count Impact
8 rooms is the base model, so every extra room adds equipment, construction, ventilation, cleaning workflow, and maintenance load. Don’t price rooms as tanks alone. Use a room-by-room count, then layer in fit-out and operating burden. More rooms can raise revenue, but they also raise readiness cost.
Water and Heating Link
$30k for specialized water treatment and heating is the bridge between tank equipment and daily use. It only works if plumbing, power, and room layout are ready, so pair it with the $150k facility build-out and plumbing budget. The real driver is integration, not just the tank price.
Installed Readiness
Budget for the site, not just the tanks. If the space cannot handle water, humidity, delivery access, and maintenance flow, the install gets slower and more expensive. The clean model is $160k for tanks, $30k for treatment and heating, and $150k for build-out and plumbing, then adjust for each extra room.
Float Room Buildout Startup Expense
Build Cost
Float rooms cost more because water, humidity, sound control, and privacy drive the build. A basic studio can skip wet-room work, but a float center needs sealed surfaces, plumbing, drainage, and quiet HVAC coordination. Budget the shell around $150k for build-out and plumbing in Months 1-4, excluding rent.
What It Covers
Estimate the shell by room count, square feet, and trade quotes. The $150k covers leasehold improvements, wet-room construction, waterproof finishes, floor drains where required, plumbing, electrical, sound isolation, lighting, and changing areas. Add $40k for HVAC and air filtration and $75k for furnishings; total core facility spend is about $265k.
Keep Costs Tight
Keep savings in the spec, not the finish. Lock the room count early, get one mechanical, electrical, and plumbing (MEP) bid set, and avoid redesign after waterproof work starts. The common mistake is trimming drains, soundproofing, or air handling; that usually creates rework, delays, and higher labor, not real savings.
Why It Costs More
This is pricier than a normal wellness studio because water and humidity affect every surface and system. Quiet HVAC, sanitation, and privacy are part of the service, not extras. That is why float centers need $265k in facility spend before tanks and equipment, while monthly rent stays outside this block.
Location Readiness Startup Expense
Lease Cash
Location cash starts before opening: lease deposit, first month’s rent of $12k from Month 1, utility setup, zoning review, landlord rules, building access, and ADA (Americans with Disabilities Act) checks. Keep this separate from CAPEX, because it is working cash needed to secure the site.
What It Pays For
This cost covers the money needed to make the location usable, not the float tanks. Build it from deposit terms, $12k rent, utility activation quotes, landlord conditions, and inspection timing. Site-readiness checks should confirm plumbing distance, slab work, tank delivery access, water capacity, electrical load, and HVAC load.
Check zoning before signing.
Get utility quotes early.
Map tank delivery access.
Reduce Site Risk
Pick a site that already fits water, power, and access needs. That can reduce plumbing, slab, HVAC, and delivery pain. Ask for landlord requirements in writing, verify zoning early, and walk the path for tank delivery before you sign. Keep this cash separate from rent in the forecast.
Use a utility-ready space.
Avoid major slab changes.
Confirm inspection timing.
Rent vs. Startup Cash
Put $12k monthly rent in operating expenses from Month 1, but keep deposits and utility setup in startup cash. That split matters: one is ongoing burn, the other is upfront outflow. If the lease starts before opening, the center pays rent before revenue, so runway has to cover that gap.
Permits, Insurance, and Compliance Startup Expense
License Rules
Float therapy does not have one national license source. State, county, and city rules can each add business registration, health or sanitation checks, building permits, and inspections, so approval is not automatic. Build the compliance plan around the exact jurisdiction, not a generic wellness template.
Cost Inputs
This budget covers business registration, legal setup, accounting setup, local health permits, building permits, inspections, liability insurance, and water quality documentation. Use local quote(s), filing fees, and inspection timing to price it. The operating model assumes $750 per month for insurance and $600 per month for accounting from Month 1.
Check state and city rules first
Price insurance before opening
Keep water logs on file
Delay Buffer
Start permits early and expect inspection delays, because a binder from the insurer may be needed before opening. The fastest way to cut cost is to avoid rework: confirm zoning, landlord rules, and local health requirements in writing before you spend on buildout. One missed permit can push opening and add carrying cost.
Compliance Cash
Plan for compliance as ongoing cash, not a one-time filing. With $750 monthly insurance and $600 monthly accounting starting in Month 1, the business carries $1,350 per month before any permit renewals or inspection fixes. That makes early documentation and local sign-off worth real money.
Pre-Opening Operations and Launch Startup Expense
Launch Cash
If you’re opening a float therapy center, this block is the cash you need before doors open. The fixed launch stack is $42k: $15k for reception and office IT, $12k for website and online booking, $8k for first retail inventory, and $7k for security and access control. Add about $3,600 per launch month for booking software, site support, and marketing.
What It Covers
This spend covers the front desk, point-of-sale setup, office IT, towels, robes, cleaning supplies, sanitation supplies, Epsom salt, staff training, branding, soft-opening marketing, and retail setup. Estimate it with vendor quotes, unit counts for consumables, software setup fees, and one-time design or training charges. One line matters: opening cash is mostly setup, not rent.
Quote software and POS first.
Count towels and robe units.
Price retail SKUs by opening stock.
Trim The Stack
Keep the expensive pieces that affect guest flow, sanitation, and trust. Bundle website, booking, and IT support where possible, and buy opening retail stock only for the SKUs you know you can sell. Don’t cut access control, sanitation, or staff training. The usual mistake is overbuying décor and underfunding launch marketing and systems.
Buy only launch SKUs.
Bundle digital setup work.
Protect sanitation and access control.
Opening Cash Check
The clean read is simple: $42k of base CAPEX plus $3,600 in monthly launch-readiness spend. That keeps this chapter in pre-opening mode only, so you can separate launch cash from ongoing rent, payroll, and member growth costs later. Any delay in staff training or soft-opening marketing can push opening day back.

Planning note: Scenario ranges are researched planning assumptions, not exact vendor quotes.
In this researched case, the 8-tank float therapy center needs $497k in startup CAPEX and $312k of minimum cash, or about $809k of funding capacity The biggest line items are $160k for tank systems, $150k for build-out and plumbing, and $40k for HVAC and air filtration
This model reaches breakeven in Month 13, after a tough first operating year Year 1 EBITDA is negative $155k, then improves to $284k in Year 2 The payback period is 38 months, so the opening budget needs enough cash to survive the early ramp-up period
Yes, equipment alone is not enough The model includes $160k for float tank systems, but the minimum cash need still reaches $312k in Month 13 Working capital helps cover rent, payroll, insurance, marketing, supplies, and customer ramp before daily visits are high enough to support the business
The researched base case uses 8 tanks, which supports a higher-capacity location but raises CAPEX to $497k A smaller first site may reduce tank purchases and buildout risk, but it can also cap revenue Test tank count against expected visits, room turnover, staffing, and lease cost before committing
Local rules can change permits, inspections, plumbing, ventilation, sanitation, water testing, and accessibility work That matters because this model already includes $150k for facility build-out and plumbing, $40k for HVAC, and $30k for water treatment and heating County and city requirements can push those figures up
