Stupid Questions about Spa & Hot Tub Covers

September 25th, 2014 by

Ask a Stupid Question DayI’ve heard lots of funny questions about hot tub covers over the years, and in honor of National Ask a Stupid Question Day, which takes place tomorrow – here’s a list of questions and answers about spa covers.

We’ve had a lot of questions about spa covers over the years, none of them actually stupid. So, I challenged a few staff members around here this week to send me their favorite questions about hot tub covers.

This is what we came up with – I hope it’s informational!

 

How much weight do spa covers hold?

That depends on the integrity of two things, the foam density and the strength of the support channel that runs across the fold. Spa covers can crack across the foam panels, or the support channel can become bent when overloaded. We like to brag that our spa covers will hold over a ton (and they will, if you place a large, evenly distributed weight across the top). But if we’re talking about a person or pet standing in a 1 sq ft area, our spa covers will support between 100-200 lbs, depending on the foam density chosen.

What options are there?

Among the basic options, we have 14 colors of marine grade vinyl, skirt length, strap length, weight and density of insulation foam. We also offer a double-wrapped core to protect from moisture, the number one spoiler of spa cover foam, and a continuous heat seal, to prevent heat loss along the fold. New this year are our heavy duty wind straps option.

What type of spa cover do you own?

Currently, I have one of our top of the line spa covers, called The Works, on my own home spa. Over the years, I’ve had better and worse, sometimes taking home mis-ordered spa tops that almost fit my tub. The spa cover I have now is performing beautifully, in it’s fourth year of service.

How long did your last spa cover last?

My very last spa cover was hit by a tree branch during a storm (one day I’ll get around to that gazebo). So, it only lasted me 2 years. I once had a cover that I kept for 10 years, until the vinyl started to split, then one of the panels cracked. If you take care of it with regular cleaning and conditioning, and “air it out” twice per week for an hour, you can expect 5-7 years from a good spa cover, if you don’t get hit with a tree, or carried off in high winds!

Dirty secrets about hot tub covers?

Most are made in Mexico or Canada – is that a dirty secret? How about the vast differences in construction techniques? I have heard of some groups that use flimsy aluminum or pvc support channels, or foam panels with less than the stated density rating. Using cardboard caps on the foam corners, to give the illusion of a thicker core. Not vacuum sealing and heat seaming the foam core, exposing the foam to constant moisture. There are ways to make a cheap spa cover, but we don’t cut corners here.

What are hot tub covers made out of?

They are made with two tapered panels of closed cell foam, wrapped in one or two layers of 6-mil polyethylene. Two or more panels are joined together, both with support channels embedded into the edge of the foam panel to provide rigidity across the center of the tub. The two panels are slid into a custom sewn ‘bag’, which is zipped up tight around the foam cores. The top and skirt material is a marine grade vinyl to resist rain and weather. Materials: Foam, Plastic, Steel, Vinyl, Nylon.

How are spa covers manufactured?

Ancient Chinese Secret! Not really, we are mighty proud of our state of the art design, manufacture and shipping facility. Your spa cover design and manufacturing is computer controlled with specific cad dimensions fed into our foam cutting, and bag sewing machines. Expert technicians vacuum wrap and heat seal the foam cores and insert them into the bag. The seam team sews it up tight, and inspectors run a 27-point drill before it’s boxed up by the shipping department.

What’s the largest spa cover ever made?

We once built a spa cover for a waterpark (read more), that was 10 separate panels, covering an outdoor hot tub that was 20′ diameter! It was quite a job, and expensive as I recall – but, they made their money back in reduced heating costs in 8 months. Not sure if it’s the largest ever made, but the largest we’ve ever done!

How much snow can a spa cover hold?

More than you think. Because it’s spread out over the top of the cover, the weight is evenly distributed. Anything under 24″ shouldn’t be a concern. Even more, if the snow is dry and light. Heavy layers of ice mixed with snow is more of a concern. If you want to remove snow from a spa cover, use a plastic shovel without metal edges.

Do wild animals damage spa covers?

Bears seem to be attracted to some particular scents contained in spa foam. We’ve done a post (with pics!) on the topic. This is very rare, and it’s never happened to one of our hot tub covers – every since we began infusing them with shark scent!

What’s the worst thing you can do to your spa cover?

The worst thing you can do to a spa cover….? Is use it as a stage, or clean it with automotive care products. Or take it on the water, for some stand-up Hot Tub Cover Boarding

Pitfalls to avoid with hot tub covers?

High Winds can fling a spa cover halfway across the county! Keep it secured. Make sure that the roof eave or gutters don’t drain directly onto your spa cover, and if you have more than a few hours per day of direct sun, put up some shading. When ordering, don’t guess at dimension, but run a measuring tape. Use a cover lifter, a lot of damage is caused by not using one – usually someone falls into the cover when it’s leaning up against a wall. Crack!

Sad stories about hot tub covers?

There are plenty of sad stories about not using a spa or hot tub cover. Preventing access of small children to hot tubs is one of the best features of a spa cover. When properly affixed, they can be an effective barrier, but when they are not used properly…

Do I really need a hot tub cover lift?

Yes, not only to save your back, but to prevent injury to the spa cover. Moving an awkward and wet spa cover around is not easy. And when they are not stored up and out of the way on a spa cover lifter, they tend to get damaged, especially at parties. They also may not be positioned optimally for drying, as they are when folded over a spa lifter arm.

Hot tub cover accessories?

Aside from cleaning and conditioning chemicals, some other nifty spa cover accessories are the Cover Cap, and the Heavy Duty Wind Straps. Floating spa blankets are an accessory worth looking at, to protect your spa cover from excess heat and moisture.
