Get More from Your Deck with a Built-In Sunken Hot Tub
Installing a hot tub sunken into your deck can transform your outdoor space and take your relaxation to the next level. Sinking your hot tub into the deck rather than placing it on top provides some great benefits that make it worth considering for your home.
We'll also provide tips to help you make the most of your built-in spa once the project is complete.
Deck Hot Tub Design Considerations
There are a few key factors to think about when planning a sunken hot tub for your deck.
Space Savings
One of the best reasons to install a hot tub into your deck is the space savings. By sinking the tub into the deck itself, you reduce its footprint and open up more usable surface area. The sunken design means you don't lose any of your existing deck layout or have to work around a large above-ground hot tub.
This makes sunken hot tubs perfect for smaller decks or patios where a full above-ground tub may be too cumbersome. The recessed installation preserves your outdoor living space for furniture, dining areas, landscaping and more.
Accessibility
When installing an in-ground hot tub, it's important to consider easy and safe accessibility. The tub should have wide steps and sturdy railings leading down into it from the deck level. This ensures users can get in and out of the hot tub without difficulty.
Access considerations also apply to maintenance and repairs. There should be adequate clearance around the sunken tub so technicians can access the internal equipment for periodic servicing. Some hot tub owners build a removable hatch into the decking above the tub to create an access point without cluttering the clean lines of the sunken design.
Aesthetics
The streamlined look of a sunken hot tub can greatly enhance your deck's aesthetic. The smooth, recessed installation creates a seamless transition from decking to hot tub. This provides a polished, upscale look perfect for entertaining and backyard relaxation.
Carefully selecting finishes like tile, stone or wood trim around the sunken tub also allows you to seamlessly integrate it into your overall deck decor. The right choices can make it look like a custom-designed feature rather than an add-on.
Sunken Hot Tub Installation Process
Installing a hot tub into your deck takes careful planning and hiring experienced professionals.
As with any major home project, the first step is thorough planning. You'll need to research local building codes to determine what permits are required for installing a sunken hot tub. Deck modification, electrical, plumbing and excavation permits are typically needed. An experienced contractor can provide guidance on permit requirements.
It's also important to hire the right pros for the job. Look for contractors specifically experienced with sunken hot tub and spa installation. They will be able to expertly handle the specialized construction and modifications involved.
Site Preparation
Once permits are in place, the contractor will prepare the installation site. This involves reinforcing the areas of decking around where the hot tub will sink into. Structural supports may need to be added beneath the deck to handle the weight of the full hot tub.
The next step is excavating the hole where the hot tub will be recessed into the decking. How far below deck level the contractor digs out will depend on the height of your selected tub model. The excavated hole is then lined with waterproofing materials.
Proper drainage is installed below the hole to control water runoff when the tub is drained. Insulation between the hot tub and decking also helps protect against condensation buildup and rotting over time.
Hot Tub Installation
With the hole dug and lined, it's time to lower the hot tub into place. The contractor will secure the tub to the surrounding deck to hold it firmly in place once filled with water. Next comes hooking up the electrical, plumbing and mechanical equipment.
Electrical work involves safely running power to the hot tub equipment and installing fixtures like lights. For plumbing, the contractor connects the hot tub's jets and drainage to water lines and PVC pipes leading below the deck. The equipment like pumps and heating unit also gets hooked up at this stage.
Finishing Touches
To complete the sunken hot tub installation, decorative finishes are added. Tile, stone or wood trim give the recessed tub a polished, built-in look. Safety railings are also installed around any steps, seats or benches leading into the sunken tub.
The final step is carefully filling the hot tub and testing all of the jets, lighting and controls. Once any final adjustments are made, you're ready to enjoy your new spa paradise!
Costs of Sunken Hot Tub Projects
Installing a sunken hot tub is a more involved project than placing a portable spa above ground, so you can expect to invest more in the process. However, the end result provides a much more integrated, luxurious backyard experience.
Costs for sunken hot tub projects can range widely, from around $3,000 on the low end up to $15,000 or more. The specific price will depend on factors like:
- The hot tub model you choose - larger higher-end tubs will cost more.
- How extensive the deck modification is to sink and install the tub.
- If you're also renovating the surrounding patio or landscaping.
- The finish materials selected - tile, stone, wood, etc.
- Any permits, site preparation and specialized labor involved.
More complex installations with extensive construction and finishing will fall at the higher end of this price spectrum. However, you can work with your contractor to stay within your budget through thoughtful hot tub selection and project scoping.
In the long run, the investment into a sunken hot tub can pay off by adding more value and enjoyment to your outdoor living space compared to above-ground hot tubs.
Enjoying Your Sunken Hot Tub
Once the installation process is complete, it's time to start soaking in your new sunken hot tub! Here are some tips to help you make the most of your built-in backyard oasis:
Safety First
Be sure to keep the hot tub's insulating cover securely in place when it's not being used. This protects the inner workings from weather and debris. Never allow unsupervised children to access the hot tub, and follow the manufacturer's safety recommendations.
Regular Maintenance
While sunken tubs don't require as much care as portable spas, you still need to drain, clean and refill the water every few months. Test and adjust chemical levels regularly per the manufacturer's instructions. Periodic filter cleaning and equipment inspection will also keep your hot tub running smoothly.
Maximize Hydrotherapy
Make the most of your hot tub's therapeutic benefits by using the various jets to target different muscle groups. Rotating through massage jets, directing water flow and adjusting air intensity provides an invigorating spa experience.
Complement the Space
Decorate the space around your sunken hot tub to enhance the atmosphere. Strategically placed lighting, cozy seating areas, privacy screens and surround sound speakers complement the spa environment. During parties, the hot tub becomes an instant highlight for guests.
