Hot Tub Store in St. Louis, MO

Hot Tub & Spa Sales in St. Louis

Choosing a new hot tub is one of the most rewarding investments you can make for your home and your wellness routine. But with dozens of brands, sizes, jet configurations, and price points available, the decision can feel overwhelming without the right guidance. That’s where working with an experienced local dealer makes all the difference.

At R&S Pool & Spa, we carry Premium Nordic Hot Tubs and Marquis Hot Tubs—two brands consistently recognized for their build quality, energy efficiency, and therapeutic performance. Nordic hot tubs are engineered for durability and simplicity, making them an excellent choice for first-time buyers who want premium performance without unnecessary complexity. Marquis spas, on the other hand, offer advanced hydrotherapy systems, customizable jet layouts, and luxury features like wireless sound systems and LED lighting that elevate the entire hot tub experience.

Finding the Right Spa for Your Space and Budget

Every backyard in St. Louis is different. A historic home in the Central West End may have a compact patio that calls for a two- to three-person spa, while a property in Chesterfield might have the room for a full-size six-person model with lounge seating. Our team walks you through the key considerations:

• Size and seating capacity: Hot tubs range from intimate two-person models to spacious eight-person designs. Consider who will use it most often and how you’ll entertain.
• Jet configuration: Different jet placements target specific muscle groups. If you’re seeking pain relief for a chronic condition, therapeutic jet placement matters more than total jet count.
• Energy efficiency: St. Louis winters mean your spa will work harder to maintain temperature. Full-foam insulation, tight-fitting covers, and efficient pumps can dramatically reduce monthly operating costs—typically ranging from $20 to $50 per month for a well-insulated model.
• Electrical requirements: Most premium hot tubs require a dedicated 240-volt circuit. We’ll help you understand what your home needs before delivery day.

We encourage every customer to schedule a test soak before making a hot tub purchase. Sitting in a filled, heated spa is the only way to truly evaluate comfort, jet pressure, and ergonomic fit. Our staff will help you compare models side by side so you leave with complete confidence in your choice.

What About Swim Spas, Saunas, and Cold Plunge Options?

The wellness market has expanded well beyond traditional hot tubs. Many St. Louis homeowners are now exploring swim spas for low-impact exercise, saunas for deep heat therapy, and cold plunge pools for recovery and circulation. If you’re interested in any of these options, our team can discuss how they complement a standard spa and help you determine which combination fits your wellness goals and available space.

Hot Tub Installation & Service in St. Louis

A hot tub is only as good as its installation. Improper setup can lead to electrical hazards, structural damage to your deck or patio, and voided manufacturer warranties. Professional installation ensures your spa is level, properly wired, and positioned for safe, long-term use.

What Professional Installation Involves

When you purchase a new hot tub, our team coordinates the entire delivery and installation process. Here’s what to expect:

• Site assessment: We evaluate your chosen location for adequate drainage, structural support, and electrical access. A filled hot tub can weigh between 3,000 and 6,000 pounds, so the surface beneath it must be able to handle the load.
• Electrical setup: A licensed electrician installs a dedicated GFCI-protected circuit as required by the National Electrical Code. This is not a DIY job—improper wiring is a leading cause of hot tub fires and electrical injuries.
• Delivery and placement: Our team manages the logistics of getting your spa into position, whether that means navigating a narrow side yard in The Hill or using a crane for an elevated deck in Kirkwood.
• Startup and orientation: Once filled, we balance your water chemistry, walk you through control panel operation, and answer every question before we leave.

Ongoing Spa Repair and Service

Even the best-built hot tubs eventually need maintenance or repair. Common issues we handle include malfunctioning heaters, low-pressure jets, noisy pumps, error codes on control panels, and slow leaks. Our service team provides fast spa repair across the entire St. Louis metro area, including Chesterfield, Ballwin, Webster Groves, and beyond.

Pro Insight: If your spa’s heater stops working during a cold snap, don’t drain the tub. Standing water in the plumbing can freeze and crack pipes within hours. Call for service immediately, and in the meantime, keep the cover on and the circulation pump running if possible.

Hot Tub & Spa Chemicals in St. Louis

Proper water care is the foundation of a safe and enjoyable hot tub experience. Unlike a swimming pool, a spa’s small volume of heated water creates an environment where bacteria and algae can multiply quickly if chemical levels are even slightly off. Consistent water treatment isn’t optional—it’s essential.

Essential Water Care Products

We stock a complete line of hot tub chemicals and water treatment products, including:

• Sanitizers: Chlorine and bromine are the two most common options. Bromine tends to perform better in hot water and is gentler on skin, making it the preferred choice for most spa owners.
• pH adjusters: Keeping pH between 7.2 and 7.8 prevents equipment corrosion and skin irritation. St. Louis municipal water typically runs slightly alkaline, so you may need a pH decreaser more often than an increaser.
• Alkalinity balancers: Total alkalinity acts as a buffer for pH, preventing dramatic swings that can damage your spa’s components.
• Shock treatments: Weekly oxidizing shock breaks down organic contaminants that regular sanitizers don’t fully eliminate. This is especially important after heavy use or when your spa starts to develop a chemical odor.
• Calcium hardness adjusters: St. Louis water hardness varies by neighborhood. Areas like Soulard and Tower Grove may see different mineral content than homes in West County. We can help you test your source water and recommend the right products.

A Simple Weekly Water Care Routine

Maintaining balanced water doesn’t have to be complicated. Most spa owners can keep their water crystal clear with about 10 minutes of attention per week:

• Test sanitizer, pH, and alkalinity levels using test strips (we carry accurate, easy-to-read options in-store).
• Add sanitizer as needed to maintain the recommended range (3–5 ppm for bromine, 1–3 ppm for chlorine).
• Apply shock treatment once per week or after every heavy-use session.
• Drain and refill your spa every three to four months, depending on usage frequency.

Expert Tip: Bring a water sample to our store anytime. We provide free water testing and will give you a precise treatment plan tailored to your specific results—no guesswork required.

Hot Tub & Spa Covers in St. Louis

A high-quality hot tub cover is one of the most impactful investments you can make for energy savings and spa longevity. In St. Louis, where summer storms send leaves and debris flying, and winter temperatures demand serious heat retention, your cover works harder than almost any other component of your spa.

Why Your Cover Matters More Than You Think

A well-fitted, properly insulated spa cover can reduce your energy costs by up to 75% compared to running an uncovered spa. The U.S. Department of Energy has continued to evaluate energy standards for portable electric spas and hot tubs, and recent discussions around federal hot tub regulations underscore how important energy efficiency has become in spa design and accessories. A cover that has lost its structural integrity—sagging in the middle, waterlogged, or cracked along the seams—can double your heating costs virtually overnight.

Signs it’s time for a replacement cover include:

• The cover feels significantly heavier than when it was new (waterlogged foam core).
• Visible tears, cracks, or deterioration in the vinyl shell.
• The cover no longer sits flush against the spa lip, allowing heat to escape.
• Mold or mildew odor that doesn’t respond to cleaning.

Cover Lifters Make a Difference

A saturated spa cover can weigh well over 100 pounds, making it difficult and even dangerous to remove without assistance. Spa covers and lifters solve this problem by using hydraulic-assist or pivot-arm mechanisms that allow a single person to remove and replace the cover in seconds. We measure and deliver new hot tub covers to homes across South City, Brentwood, Maplewood, and the greater St. Louis region, ensuring a precise fit for your specific model.

Hot Tub & Spa Filters in St. Louis

Your spa’s filtration system is its first line of defense against cloudy, unhealthy water. Filters trap body oils, lotion residue, hair, and fine particulates that chemicals alone cannot remove. Over time, even well-maintained filters lose their effectiveness and need to be replaced.

Filter Maintenance Schedule

Following a consistent filter maintenance routine will extend the life of your cartridge and keep your water quality high:

• Every two weeks: Remove the filter cartridge and rinse it thoroughly with a garden hose. Use a spray nozzle to work between each pleat where debris accumulates.
• Every three months: Soak the filter overnight in a dedicated filter cleaning solution to dissolve embedded oils and minerals that rinsing alone cannot remove.
• Every 12 to 18 months: Replace the filter cartridge entirely. Even with diligent cleaning, filter media degrades over time, and flow rates decrease.

Pro Insight: Keep a spare filter on hand so you can rotate while one soaks in cleaning solution. This ensures your spa is never running without filtration, which can cause rapid water quality degradation—especially during heavy-use periods like holiday weekends.

Finding the Right Replacement Filter

Spa filters are not universal. The correct replacement depends on your spa’s brand, model, and year of manufacture. Bring your old filter into our store or share your spa’s model number, and we’ll match you with the exact cartridge you need. We stock spa filter replacements for all major brands, including Marquis, Nordic, Cal Spa, Hot Spring, FreeFlow Spas, and many others.

Spa Accessories & Replacement Parts in St. Louis

The right accessories can transform a basic hot tub setup into a true backyard oasis. Whether you’re looking to enhance comfort, improve functionality, or replace a worn-out component, having access to a wide selection of quality parts makes all the difference.

Popular Spa Accessories

Our customers across neighborhoods like The Hill, Lafayette Square, and Creve Coeur frequently ask about these upgrades:

• Spa steps: Matching steps improve safety and aesthetics, especially for raised installations.
• Headrest pillows: Replacement pillows restore comfort that degrades from UV exposure and chemical contact over time.
• Drink trays and towel bars: Small additions that significantly improve the relaxation experience.
• Wireless sound systems: Bluetooth-compatible speakers designed for wet environments let you enjoy music without risking standard electronics.
• Aromatherapy cartridges: Spa-safe essential oil systems add a sensory dimension to your soak without affecting water chemistry.

Common Replacement Parts We Stock

Worn or broken parts don’t have to mean an expensive service call. Many common repairs are straightforward for handy spa owners, and we carry the components you’ll need:

• Jets: Individual jet inserts that twist out and snap in without tools. Cracked or discolored jets are one of the most common replacements.
• Pumps and motors: Circulation pumps and jet pumps for all major brands.
• Heater elements: The component most likely to fail in hard-water areas.
• Control panels and topside overlays: Faded or unresponsive buttons can be replaced without a full control system overhaul.
• Plumbing fittings and gaskets: O-rings, unions, and valves for addressing leaks at connection points.

R&S Pool & Spa is known for having the largest selection of pool and spa parts in the St. Louis area. If we don’t have a specific part on the shelf, we can typically special-order it within a few business days. Our team will also help you identify the correct part number and walk you through the replacement process if you prefer a DIY approach.
