Day rate + delivery + attendant + generator — and the year buying beats renting
| Unit | Low | Typical | High | What you get |
|---|---|---|---|---|
| Standard dry 13x13 | $100 | $175 | $275 | Bounce area, mesh sides; the classic |
| Bounce + slide combo (dry) | $200 | $300 | $450 | Bounce area plus attached slide |
| Wet/dry combo | $250 | $350 | $550 | Water hookup, splash pool; summer favorite |
| Obstacle course | $400 | $525 | $700 | Two-lane racing; eats 40+ feet of lawn |
| ~20-ft standalone waterslide | — | ~$250 | — | Slide only, no bounce floor |
Day rates for the usual 4-8 hour rental window with setup and teardown included (Thumbtack's 2025 pricing guide, Texas Jump N Splash, regional rental yards). Metro reality check: the same 13x13 runs about $114-$134 in Salt Lake City, $150 in Miami, $200+ in Dallas, and full-day packages in some Texas markets span $200-$700.
| Add-on | Typical | Range | When you need it |
|---|---|---|---|
| Delivery (local) | $50 | $25-$75 | Often free within 15-20 miles — ask |
| Delivery (extended) | $100 | $75-$150 | Beyond the yard's home radius |
| Attendant | $35/hr | $25-$45/hr | Parks and many insurers require one |
| Generator | $100 | $50-$150 ($150-$200 in LV-class markets) | No outlet within ~50 ft — most park setups |
| Weekend keep | +50% | +0-100% | Fri pickup, Mon return; negotiate this |
Surprise-fee watchlist from rental yards' own fee pages: the generator is the most common unbudgeted line (Celebrate Kids LV quotes $150-$200 per generator and $45/hr attendants), and the attendant is often mandatory, not optional, once insurance reads "park" on the permit.
Rental yards quote a day rate for the unit, then bolt on delivery, labor, and power. This calculator prices the unit class you picked at the day-rate bands above, applies the weekend multiplier, and stacks every add-on at its going rate — then answers the birthday-every-year question: when does buying beat renting?
Unit subtotal = day rate × rental-length multiplier (1 day ×1, weekend keep ×1.5 typical, two days ×2). Total = unit subtotal + delivery + (attendant hours × $35) + generator. Low and high estimates swap in the ends of every band. Buy-vs-rent break-even = $400 residential purchase price ÷ your typical total — the number of rentals it takes for buying to pay for itself.
Pick the unit class first — it's 60-80% of the bill. A wet/dry combo in June costs $175 more than the dry unit it's based on; same party, same kids, hotter day. Then be honest about power: if the party's at a park, tick the generator. If it's in your backyard within extension-cord reach of an exterior outlet, don't. The attendant matters mostly for parks and big groups; in most states it's your call at a private backyard party.
The backyard summer party: wet/dry combo ($350 typical), local delivery ($50), a 4-hour attendant ($140 at $35/hr), generator for the far corner of the yard ($100). Typical total: $640, with the range running $425-$955. Add the weekend keep (+50% on the unit, +$175) and you're at $815 — worth it only if Sunday's party two exists.
The lean birthday: standard dry 13x13 ($175), delivery included by the yard down the street, your own outlet, no attendant. Total: $175 ($100-$275 range). And the buy-vs-rent math on this one: a $400 residential unit pays for itself in 2.3 rentals at this rate — by the third birthday, the family that buys is renting free.
A standard 13x13 dry bounce house rents for $100-$275 a day, with $175 typical across markets. A bounce house with a slide runs $200-$450, a wet/dry combo $250-$550, and obstacle courses start around $400. Most quotes cover a 4-8 hour day with setup and teardown included — the add-ons are what move the bill.
Three add-ons do most of the damage. Delivery runs $25-$150 depending on distance (some yards include local delivery). An attendant costs $25-$45 an hour — parks and some insurers require one. A generator rental adds $50-$150 when there's no power outlet within about 50 feet, which is most park setups. A wet/dry combo with local delivery, a 4-hour attendant, and a generator comes to $640 typical, range $425-$955.
Wet/dry combos rent for $250-$550 a day ($350 typical) — roughly $100-$200 more than the same unit dry, because water hookups, drainage, and extra cleaning are involved. Standalone waterslides around 20 feet run about $250, and big multi-lane slides climb from there. Houston-style markets price water combos $300-$550; drier markets quote the low end.
For a once-a-year birthday, no — a residential bounce house costs $250-$600 (about $400 typical), versus $175 to rent the basic unit. That's a 2.3-rental break-even, so buying pays off by the third birthday IF you use it that often and store it. Commercial-grade units run $1,500-$3,500 and only make sense if you're the one renting it out. Residential units wear out faster and carry smaller weight limits — check the label.
Usually, but with strings attached: most parks require a permit, proof of insurance from the rental company, stakes instead of sandbags (or the opposite on pavement), and often a staffed attendant. Since parks rarely have power within blower-cord range, budget the generator add-on ($50-$150). Some rental companies won't deliver to parks at all — ask before booking the pavilion.
Local density. This is a hometown industry with thin margins and real delivery costs, so the same 13x13 unit runs $114 in Salt Lake City, $150 in Miami, and $200+ in Dallas. Multi-day and off-season discounts are common and negotiable — many yards let weekend rentals keep the unit until Monday for half the day rate again — so the quote you get on the phone often beats the website price.
