how much does it cost to add a spa to an existing pool Just thinking about a nice, long soak in warm, bubbling water washes away stress. The real thing is even better. The warm water and invigorating jets of a spa can combat stress, ease aching joints, reduce muscle stiffness and increase circulation.

When you relax in a spa, the buoyancy of the water supports most of your weight, giving your joints a well-deserved break.

Arthritis? Back pain? Trouble sleeping? Try a soak in a bubbling spa.

All this sounds great, you say. Too bad I didn’t spring for a spa when I had my pool installed.

Well, it’s not too late. You can add a spa to an existing pool. Here’s a look at what it might cost to install a hot tub along with some options.

Installing A Stand-Alone Spa

in ground hot tub costs and adding hot tub to existing poolThe easiest, most affordable solution is to add a stand-alone spa near your pool. This is the standard fiberglass hot tub with a wooden skirt and its own pump and electric system.

Installing a detached spa can be a great choice. Maybe you want your spa to be in a more secluded area of your yard. Choose a stand-alone spa, and you can enjoy it closer to your patio or just outside your bedroom.

Maybe you’re happy with your pool and its surroundings just the way they are, and you don’t want to mess with a good thing. Perhaps you’re not crazy about construction upheaval all over again. Or you want a more budget-friendly choice.

All good reasons to consider a stand-alone spa.

A stand-alone spa will need its own pump and filtration equipment and you’ll need to test the spa water daily, in addition to keeping an eye on your pool water quality.

The cost: between $6,000 and $15,000, depending on the model you choose.

How Can I Add a Spa To A Vinyl-Liner Pool?

You’ll see this option referred to as a spill-over spa. It’s placed directly adjacent to your pool, allowing for the spa and pool water to mingle together.

This option involves adding a preformed fiberglass shell that connects to your pool.

A spill-over spa will tie into your pool’s plumbing system and share its pump, filter, and heater. The spa and pool will share the same water, too, so there’s no separate testing or pH level balancing needed.

The same kind of construction you experienced with your pool installation will happen again for the spa addition.

An excavator will show up to dig up part of your patio or pool decking to create a hole for the shell. Crews will install plumbing, electrical and masonry.

The cost, including the spa shell and the installation, will be about $15,000.

How Can I Add A Spa To A Gunite Pool?

the cost to install a hot tub next to an existing gunite pool is the most expensive optionThis, frankly, isn’t a great option, unless money is no object.

Adding a spa to an existing gunite pool is practically like creating another gunite pool. It will cost you nearly as much as you paid for the pool — as much as $50,000 — even if it’s just a 10-foot by 10-foot spa. The construction techniques to install gunite are considerably more involved than with a vinyl-liner pool, which explains the added cost.

When is the Best Time to Add a Hot Tub to My Pool?

If you haven’t had your pool built yet, now is the time to consider adding a hot tub or spa. Constructing it when the pool goes in will cost a fraction of what it would to add it later — from $8,000 to $25,000.
