Indoor swimming pools are a luxurious and convenient way to enjoy swimming throughout the year, no matter what the weather outside may be. The pools can be designed in many different styles and shapes, with unique features and ideas that make them stand out.

Read on to explore design ideas that can transform your indoor pool into a calming oasis.

14 Stunning Indoor Swimming Pool Design Ideas

Whether you’re browsing broad indoor pool ideas or looking specifically for small indoor pool ideas to fit a tighter space, the following styles cover the full range homeowners typically consider — and most can be scaled up or down depending on your available square footage.

1. Simple Pool

This is for those who prefer a clean and minimalist design. This design features a large, rectangular pool surrounded by sleek and simple décor. Large windows allow natural light to fill the space, creating a bright, airy atmosphere. The pool may also include underwater lighting and a jet system for a spa-like experience.

2. The Clubhouse Pool

This design is perfect for those who want to recreate a resort-style atmosphere in their home. The clubhouse pool is typically designed with a large open space surrounded by windows and features high ceilings. The pool is often the centerpiece of the space, with lounging areas, a bar, and a fireplace nearby. This design can also include tropical plants and waterfall features to create a relaxing and inviting atmosphere.

3. Mid-Century Style Pool

The midcentury-style is perfect for those who appreciate the sleek and modern designs of the 20th century. This design incorporates bold colours, geometric shapes, and retro décor. Large windows allow natural light to flood the space, creating a bright and vibrant atmosphere. A built-in bar or lounge area may also be included in the design.

4. The Tree House Pool

This striking design is perfect for those who want a bit of whimsy and nature in their indoor swimming pool. The pool is typically designed with a glass roof and large windows that allow natural light to pour in. The pool is often surrounded by lush greenery, with a wooden deck or patio area for lounging. This design can also include a waterfall feature, creating a peaceful and serene atmosphere.

5. Private & Relaxing Retreat

This design is perfect for an indoor swimming pool that feels like a private retreat. Its design offers a more intimate and cozy feel, with a smaller pool and comfortable seating. The pool may be surrounded by stone or wood accents, with a fireplace or other cozy features nearby. This design is perfect for those who want a quiet and peaceful space to unwind.

6. Indoor Pool for Laps

This design is perfect for those who want to exercise in their indoor swimming pool. It is typically designed with a long, rectangular shape, with a dedicated lane for swimming laps. The pool may include other features such as underwater lighting, a jet system for resistance training, and a diving board for more advanced swimmers. This year-round access is one of the biggest reasons homeowners choose indoor over outdoor when fitness is the main priority.

7. Japanese Indoor Pool

This one is perfect for those who appreciate the beauty of simplicity and nature. This design incorporates natural materials such as stone and wood, with a focus on clean lines and minimalist décor. A zen garden may also be incorporated into the design, with a koi pond or water feature adding to the serene atmosphere.

8. Mediterranean Style Indoor Pool

This pool is perfect for those who love the warmth and beauty of the Mediterranean. This design incorporates warm, earthy tones and materials such as terracotta tiles and wrought iron accents. The pool is typically designed with a curved shape, with features such as a built-in spa and a waterfall creating a luxurious and relaxing atmosphere.

9. French Style Indoor Pool

This design incorporates ornate details such as decorative molding, chandeliers, and marble accents. The pool is typically designed with a curved or oval shape, with large windows and a skylight allowing natural light to fill the space. The design may include a built-in sauna or steam room for added luxury.

10. The Pool Room

This indoor swimming pool design is perfect for those who want a more traditional approach. It is typically designed with a classic and elegant feel, with a large rectangular pool and simple yet sophisticated decor. The pool is often surrounded by marble or stone tiles, with chandeliers and other luxurious lighting fixtures adding to the ambiance.

11. Indoor Pool with a Bar Lounge

A pool is not just for swimming; it can also serve as a social gathering spot. An indoor swimming pool with a bar lounge is the perfect design for those who enjoy entertaining guests. This design incorporates a built-in bar or lounge area that overlooks the pool, creating a space where guests can relax and enjoy drinks while taking in the beautiful surroundings.

12. Indoor Pool with Glass Walls and Ceiling

An indoor swimming pool with glass walls and ceiling is a unique and stunning design. It allows for an unobstructed view of the surrounding landscape and sky, creating a sense of connection with the outdoors. Large glass walls and a glass ceiling create a bright and airy atmosphere, and the pool may also include underwater lighting for a dramatic effect at night. This design is perfect for those who appreciate modern and innovative designs.

13. Screened-In Indoor Pool

A screened-in indoor swimming pool is the definition of getting the best of both worlds. With transparent screens, you can enjoy the beauty of your backyard and natural sunlight, just as you would with an outdoor pool, while still getting the maintenance and temperature-control benefits of an enclosed space. The screened design keeps out debris and bugs while letting the outdoor view remain part of the experience — a strong option for homeowners who love the tree house or Mediterranean styles above but don’t want to give up the outdoor feel entirely.

14. Earthy & Rustic Indoor Pool

If natural tones and textures appeal to you more than polished luxury, an earthy rustic indoor pool is worth considering. This design brings in raw elements — exposed stone, natural wood, and greenery — paired with warm yellow lighting to enhance the natural feel. A small fireplace or fire feature nearby completes the effect, blending the classical elements of earth, water, air, and fire into one cohesive space. It’s a particularly good fit for homeowners drawn to the Japanese or Tree House styles but wanting something a little less formal.

Real-World Indoor Pool Inspiration

Sometimes the best design ideas come from looking at pools that already exist. A few architecturally significant examples show just how far indoor pool design can go:

The Roman Pool at Hearst Castle in California, designed by architect Julia Morgan between 1919 and 1947, remains one of the most striking indoor pools ever built. Its most memorable feature is gold-infused blue glass mosaic tiles running from floor to ceiling, paired with replica Greek and Roman statues — a Roman bath aesthetic taken to its most opulent extreme. While few homeowners will replicate this scale, the underlying idea — using the tile and material choice itself as the design statement, rather than just the pool shape — translates well to a residential project.

Architect Albert Frey’s 1946 indoor-outdoor pool, designed for industrial designer Raymond Loewy, offers a very different lesson. The pool runs the entire length of the home, indoors and outdoors, with the indoor portion’s walls doing double duty as a bar counter. It’s a strong example of a pool designed to be genuinely lived around, not just swum in — a principle that applies directly to the Indoor Pool with a Bar Lounge concept above.

Creating a Mesmerizing Ambiance

The pool shape and style get most of the attention, but the surrounding details — ceiling, lighting, and structural accents — often do more to set the mood than the water itself.

Ceiling Design

The ceiling is often the most overlooked surface in indoor pool design. A soft blue or serene white finish echoes the sky and water below, while a mural or artwork depicting an underwater scene or landscape can turn a plain ceiling into part of the pool’s theme.

Lighting

LED strip lights along the pool’s edges add a soft glow and can be adjusted to different colours for different moods — energizing for a morning swim, calming for an evening one. Underwater LED lights that shift colour create a genuinely dramatic visual effect after dark, and pair particularly well with the Glass Walls and Ceiling or Clubhouse Pool designs above.

Decorative Ceiling Beams

Exposed beams — real wood or a more affordable faux finish — add architectural texture to an indoor pool room that might otherwise feel flat. Recessed lighting built into the beams themselves adds warmth without competing with the underwater lighting below.

Fire Features for Indoor Pools

Fire and water together create a striking visual contrast, and fire features have become one of the more requested additions to indoor pool designs in recent years. Stone fire pits are a popular choice — they’re both decorative and functional, doubling as a genuine heat source during colder months, and they pair especially well with the Mediterranean, Japanese, and Earthy & Rustic styles above. For a subtler effect, candle-style fixtures combined with LED lighting create ambiance without the same heat output.

One point worth flagging directly: fire features indoors require proper ventilation planning, the same way the pool itself does for humidity. This isn’t something to add as an afterthought — it needs to be part of the mechanical design from the start, which is exactly why working with an experienced indoor pool builder matters for this specific feature.

Key Elements for Indoor Swimming Pool Design Process

Here are some crucial factors to keep in mind when planning your indoor swimming pool design:

Size and Space: The size of the pool will depend on the intended use and the available space. A lap pool, for example, requires a longer and narrower design, while a family pool may require more space. Homeowners should consider the space needed for the pool, pool deck, and additional features such as a built-in spa, bar, or seating area.

Lighting: Homeowners should consider incorporating natural lighting through skylights or large windows to provide a bright and open environment. The pool may also include underwater lighting, creating a stunning visual effect and setting the mood for relaxation and tranquility.

Ventilation and Humidity: Indoor swimming pools can create high humidity levels, which can lead to mold growth and structural damage. Therefore, it’s crucial to consider proper ventilation and humidity control systems.

Maintenance and Upkeep: Homeowners should consider the cost and time required to maintain the pool, including cleaning, chemical treatment, and equipment upkeep. Hiring a professional pool service is also essential to ensure the pool is well-maintained and any issues are addressed promptly — see our indoor pool maintenance tips for a full breakdown of what ongoing care actually involves.

Building Permits and Codes: Before planning an indoor swimming pool, homeowners in Toronto should be aware of the local building codes and regulations. Obtaining the necessary permits and approvals is essential to ensure the pool meets safety standards and is built to code. Consulting a professional pool company for indoor swimming pool design guidelines specific to your municipality is the most reliable way to avoid a design that later fails inspection. Our indoor pool installation guide walks through what the build and permit process actually looks like.

Luxury Features for Your Indoor Swimming Pool

Every feature below adds to the overall project cost, so it’s worth reviewing our indoor pool cost guide alongside this list to see how these additions typically affect your budget.

Lighting can set the mood and create a stunning visual effect. LED lights that change colours or dimmer switches can create a relaxing and luxurious atmosphere.
A built-in hot tub or spa area can provide additional space for relaxation and hydrotherapy.
A sound system or underwater speakers can create a lively or soothing ambiance, depending on the music or sound effects played.
Automated pool covers provide convenience and safety by allowing homeowners to easily cover and uncover the pool when not in use.
Automatic chemical dosing systems can help maintain proper pool chemistry and eliminate the need for manual testing and adding chemicals.
Outdoor living spaces, such as a patio or deck connected to the indoor pool area, can provide additional space for entertaining and relaxing.
In-pool seating or loungers can add comfort and relaxation to the swimming experience, allowing swimmers to sit and enjoy the water without having to tread water.
Automatic pool cleaners can save time and energy by cleaning the pool regularly, eliminating the need for manual cleaning or hiring a pool service.
A retractable pool enclosure can provide the benefits of both an indoor and outdoor pool by allowing homeowners to open or close the enclosure as needed.
A diving board or slide can add a fun and adventurous element to the pool area for kids and adults.
A sauna or steam room can provide additional relaxation and health benefits, such as reducing muscle tension and improving circulation.
Artwork or decor such as sculptures, paintings, or plants can add a personalized touch and enhance the overall aesthetics of the indoor pool area.

Frequently Asked Questions

What is the most popular indoor swimming pool design?

Minimalist and clubhouse-style designs remain the most requested, though earthy rustic and screened-in styles have grown in popularity for homeowners who want a less formal, more nature-connected feel.

Can I add fire features to an indoor pool safely?

Yes, but proper ventilation must be planned as part of the mechanical design from the start, similar to how humidity control is planned for the pool itself. This isn’t something to retrofit later.

What lighting works best for an indoor pool?

A combination of natural light from skylights or large windows, plus LED strip lighting along the pool’s edges and colour-changing underwater LEDs, covers both daytime brightness and evening ambiance.

Do indoor pool design ideas need to match the rest of the house?

Not necessarily, but it usually looks more intentional when the pool room’s materials and colour palette reference the home’s existing style, even if the room itself has its own distinct character.
