Hot Tub Covers

Hey everyone!

so i finally did it—i got a hot tub!! it's so chic and i'm so obsessed. the only accessory i'm really familiar with is the hot tub cover (i've been checking out hottubcovers.com and their stuff looks amazing), but now i'm trying to figure out how to make my spa space look super aesthetic.

any ideas for other accessories? I'm looking for anything that will make the space more beautiful and relaxing. drop your best tips below!

no but hear me out.

we have a hot tub. had the same cover on it for almost three years. it looked fine. a little faded, maybe. whatever.

then the electricity bill did something weird and we started tracing it back and it was — the cover. the foam inside had absorbed water over time and lost basically all its insulating ability. the heater was running constantly trying to compensate and we just. hadn't noticed because we never actually looked at the cover.

turns out waterlogged spa covers are one of the most common reasons hot tub running costs creep up without any obvious explanation. a worn-out cover can cost you up to $180 extra a year just in heat loss. silently. invisibly. while looking totally okay from the outside.

the signs we missed:

— it got heavier to lift (we just adapted without noticing) — faint musty smell we blamed on the water chemistry — slight sagging in the middle — vinyl cracking along the fold line

all classic failure signals. we just didn't know what we were looking at.

replaced it with a custom-fit cover from HotTubCovers.com — they build them to your exact measurements which genuinely matters because a cover that doesn't seal properly at the corners defeats the whole point. used their measuring guide to get the corner radius right (would have gotten that wrong otherwise).

heater runs noticeably less now. cover lifts easily. water chemistry has been more stable.

genuinely annoyed it took us this long but also glad we finally sorted it. if you have a hot tub and you've been ignoring the cover — go lift it right now and actually pay attention to the weight. you might be surprised.

no really. sit with that for a second.

you're out here keeping your water chemistry perfect. checking the pH. cleaning the filters. protecting a $6,000–$15,000 investment with actual effort.

and then there's the cover. just… sitting there. looking fine from the outside. doing absolutely nothing on the inside.

here's the thing nobody tells you when you buy a hot tub:

a spa cover doesn't fail loudly. it fails quietly, slowly, and expensively.

the foam inside your cover has a vapor barrier. when that barrier breaks down — from UV exposure, chemical fumes off the water, heavy snow, or just time — moisture gets in. the foam absorbs it. the cover gets heavier. the insulation drops.

a new cover: R-value of 12–16. a waterlogged cover: R-value of maybe 2.

that's the difference between a cozy insulated lid and a wet cardboard box sitting on top of your 104°F water while your heater runs constantly trying to compensate.

your electricity bill is not a coincidence.

so how do you know when your spa cover has given up on you?

lift it.

not just flip it back — actually try to gauge the weight. covers for a mid-size tub should be in the 40–65 lb range. if yours feels like you're lifting a soaking wet mattress, the foam is saturated and it's done.

other signs:

→ you need two people to move it when you used to do it solo → soft spots when you press down on the surface → the center is sagging instead of peaked → it smells like mildew even after cleaning → your heating costs crept up and you can't explain why

any one of those = it's time

and when it IS time, please don't just grab whatever's cheapest

this is where people make the second mistake after ignoring the cover too long.

hot tubs are not standard sizes. they have different corner cuts, radius curves, asymmetrical shapes, speaker pockets, all kinds of variations. a cover that doesn't fit your exact tub creates gaps, leaks heat at every edge, and puts uneven pressure on the foam — accelerating the same waterlogging problem you just replaced.

what you actually need is a spa cover replacement built to your specific tub's measurements. not a "fits most" situation.

hottubcovers.com does fully custom covers built to your exact shape and dimensions — rounded rectangle, circle, octagon, cut corners, whatever your tub is — starting at $409 with free shipping across the US. if you know your brand and model, you can also shop by manufacturer and skip the measuring entirely.

vinyl vs weather shield: there's actually a difference worth knowing

vinyl (the classic): marine-grade, durable, works well in most climates. can crack over time in extreme heat or prolonged cold.

weather shield (the newer one): 100% solution-dyed polyester, about 3x stronger by tear resistance, roughly 25% lighter, and built to resist UV + mildew more aggressively. better for harsh climates, easier to lift every day.

you can literally browse color options for both before you order which is kind of satisfying

the part that always gets people:

replacing a quality spa cover costs roughly $400–$500.

running a waterlogged cover through a single winter can cost you that much — or more — in excess heating alone.

it pays for itself. usually faster than you'd expect.

if your cover is over 4 years old, do the lift test this week. if it feels wrong, it probably is.

your hot tub deserves a cover that's actually doing its job 💙

(not sure how to measure for a replacement? their measuring guide is genuinely easy to follow — takes about 10 minutes with a tape measure)

A waterlogged spa cover doesn't just look bad sitting there.

It's actively killing your heat retention. Your heater kicks on at 2am trying to compensate. Your energy bill creeps up month after month. And most people blame everything except the one thing sitting right on top of their tub.

If your cover feels heavier than it used to — the foam is already soaked. That's not insulation anymore. That's dead weight.

Here's what actually fixes it 👇

✔ Get a custom-fit hot tub cover — not a universal one that gaps at every edge and leaks heat all night

✔ Measure properly before you order — this guide saves you from a very expensive mistake

✔ If you're in a cold or high-UV climate, go Weather Shield over standard vinyl — lighter to lift, tougher in every season

✔ Match your cover to your actual spa brand — browse by brand here for a seal that actually works

✔ Free shipping anywhere in the US — no excuse to keep putting it off

Maintain what you get too. Condition the vinyl, clear standing water fast, and never let anything heavy rest on top. Full cover care breakdown here if you want your cover lasting 5+ years instead of 2.

Small fix. Big difference on the bill.

You spent thousands on the tub itself. the dealer was SO helpful right up until the moment you signed. and then two years later you're dragging this waterlogged 80-pound slab off your spa every morning wondering why it feels like it absorbed an entire lake overnight.

it did. that's exactly what happened.

the foam core gets wet from the inside because the vapor barrier — the thing that's SUPPOSED to stop moisture from getting in — was cheap to begin with. it fails. water gets in. it never comes out. and now you're fighting a cover that's actively making your energy bill worse while also being a physical hazard to lift.

and the wild part? your water chemistry probably accelerated the whole thing. low pH water creates chlorine vapors that eat the underside of the cover from below. nobody at the dealership mentioned that. nobody mentioned any of this.

the good news is a proper spa cover replacement — one actually built with decent foam density and a real vapor barrier — fixes all of it. brands like Caldera, Hot Spring, Jacuzzi, Sundance — there are covers made specifically for your model that won't fail in two years. custom ones too if your tub is an odd shape or older.

anyway. check your spa cover. if it's heavy, it's already gone.

your spa cover is quietly running up your energy bill and most people don't notice until it's way too late.

your cover is already failing if:

🔴 it feels heavier than it used to - waterlogged foam = zero insulation 🔴 mold keeps coming back on the underside - vapor barrier is gone 🔴 you see cracks along the center fold - water is getting in fast 🔴 gaps between the cover skirt and cabinet - heat escaping 24/7

the math that'll change your mind:

a failing spa cover can add $30–75/month to your energy bill.

a proper spa cover replacement costs $350–500.

do the math. the delay is costing you more than the replacement.

before you order — measure these 3 things:

1. length + width (lip to lip, not the cabinet edge)

2. corner radius (most spas have rounded corners)

3. skirt depth (the hanging flap)

get it wrong and the cover won't seal. full measuring guide here.

vinyl or weather shield?

→ vinyl = great for moderate climates, needs conditioning every 1–2 months → weather shield = 3x stronger, 25% lighter, built for harsh winters + intense sun

okay so. hot tub owners. we need to talk.

not about water chemistry (though also that). not about jets. not about the debate over whether 102°F or 104°F is the correct temperature (it's 103°F, this is not up for discussion).

we need to talk about the cover.

your hot tub cover is either saving you money or silently draining it. there is no in between.

here's the thing most spa owners don't realize until it's too late:

a hot tub cover isn't just a lid.

it's insulation. it's a vapor barrier. it's a safety feature. it's the thing standing between your heated water and the entire outdoors trying to cool it down every single night.

when it works: your heater runs normally, your water stays balanced, your energy bill is chill (unlike your tub, which is warm, ideally).

when it fails: your heater runs constantly, your chemicals get weird, your cover gets so waterlogged that lifting it off requires the energy you were trying to save for the soak.

signs your spa cover is done and you're just not accepting it yet

✦ it's noticeably heavier than it used to be (waterlogged foam. the vapor barrier failed. it's absorbing moisture and pulling heat OUT of your tub.)

✦ it sags in the middle when it rains

✦ the vinyl is cracking, fading, or peeling at the corners

✦ there are gaps between the cover and the cabinet — even small ones

✦ your energy bill has been quietly going up and you blamed… everything else

✦ it smells. you know the smell.

✦ it's been more than 6–7 years and you've never replaced it

if you said yes to two or more of those: it's time. I'm sorry. it's time.

the part where brand actually matters

not all spa covers are built the same. and not all spas are built the same.

if you own a Hot Spring Spa — one of the most popular premium spa brands out there — your tub has specific dimensions, corner radii, and a footprint that a generic "large spa cover" simply won't seal correctly. the Grandee, the Jetsetter, the Sovereign — these aren't one-size-fits-all shapes. a gap at the corner of a Hot Spring cover is energy walking out the door, every night, forever.

same goes for Coleman Spas. Coleman tubs vary by production year and model in ways that make generic covers a gamble. you want the cover that was actually measured for your tub. not "should fit most Coleman models." yours.

what to look for when you replace it

because I know someone is going to screenshot this and actually go shopping:

foam density: 2 lb minimum. 2.5 lb if you live somewhere cold.

taper: 4"/2" is the standard (4 inches thick at center, 2 at the edges). steeper taper = better drainage = less weight stress over time.

vapor barrier: heat-sealed poly wrap around each foam panel individually. this is what keeps the foam dry. if it's not heat-sealed, skip it.

vinyl: marine-grade, 32 oz, UV inhibitors built in. the sun is not kind to outdoor vinyl. don't cheap out here.

safety straps: four-point. non-negotiable if you have kids or pets.

the measuring thing (don't skip this)

measure the outside edge of the cabinet lip.

not the water surface. not "approximately rectangular." the actual outer dimension of the rim your cover sits on.

corner radius matters too — 3", 4", 5", 6" — and getting it wrong creates the gap that ruins everything.

there's a proper measuring guide here that walks you through it with diagrams. measure twice. order once.

and once you have a good cover: take care of it

✦ clean and condition the vinyl every 3–4 months. dedicated vinyl cleaner only — no household products, no petroleum-based stuff, they destroy the UV protection.

✦ clear snow and standing water promptly. the weight stresses the foam and the hinge.

✦ get a cover lift. it protects the cover from the dragging and torquing that kills hinges early. also your back will thank you.

✦ after heavy chemical treatments, leave the cover cracked for 20–30 min to let gases off. those gases eat the underside of your cover from the inside.

the tl;dr for the people who scrolled straight here

🌊 old/bad cover = heater runs more = higher bills = degraded water = sad tub

🌊 Hot Spring Spa cover → get one built for your specific model

🌊 Coleman Spa cover → same deal, don't guess on sizing

🌊 measure your tub correctly first → cabinet lip, not water surface

🌊 2 lb foam + heat-sealed vapor barrier + marine vinyl = the combo you want

🌊 replace it before it fails completely → the slow energy drain costs more than a new cover

🌊 don't know your brand? full spa brand catalog here — Jacuzzi, Artesian, Sundance, Bullfrog, Caldera, and 40+ more

your hot tub is a whole investment. the cover is the one thing protecting that investment 23 hours a day.

okay so hear me out.

if your spa cover is heavy as heck to lift, smells a little funky, or looks like it's been through three winters too many, it's not just an eyesore. it's quietly running up your electricity bill every single month.

a worn-out cover = heat escaping = your heater working overtime = 💸 gone.

signs it's time for a spa cover replacement:

it weighs way more than it used to (waterlogged foam is the culprit)

there's a musty smell that won't go away

the vinyl is cracking or fading

it doesn't sit flush on your tub anymore

honestly the fix is simpler than most people think. a good custom-fit replacement cover from somewhere like HotTubCovers.com, free shipping, made to your exact measurements, fits basically every spa brand out there.

one purchase and your hot tub is actually efficient again. worth it.
