Platinum Landscapes is a Salt Lake City, UT pool design and installation contractor that can handle any kind of pool interior project. All concrete/gunite Salt Lake City swimming pools & spas we install require the installation of an interior surface before the pool is filled with water. 

Plaster is the most common choice.    

These surfaces start off cheap but can get expensive once swimming pool designs begin using custom colors, pebble or glass beads are added to the mix. 

The alternative to plaster for Salt Lake City pool design is a fully tiled interior. 

The installation of either ceramic tiles or glass mosaics can be significantly more expensive however it is becoming the best option for clients seeking a high end finish. 

Outlined below is some further information of the different grades of interior finishes and their relative costs.


The most luxurious and durable of all interior surfaces, tiles are the most expensive option for any pool and spa interior. 

Whilst it is traditional to use a tile around the waterline of a pool or spa extending those tiles into the rest of the interior is becoming more and more popular. 

Tiles offer limitless design possibilities, are easy to maintain and are much more comfortable than plaster or pebble interiors. 

This is most important in spas, bench areas and steps where a plaster or pebble finish can feel rough or abrasive. 

There are two types of tiles commonly used in pools and spas: ceramic and glass mosaics. 


The most common choice, these tiles are reasonably cost effective and come in a wide variety of sizes and colors.   

Made from clay and permanently hardened by heat they are finished with a extremely dense decorative glaze. 


Glass mosaics are uniquely beautiful and provide a stunning finish to any pool or spa interior. 

Available in a range of solid, translucent or shimmering blends glass mosaics are the ultimate choice for any high end swimming pool or spa. 


The most popular type of interior finish for pools in Salt Lake City and the surrounding communities. It is the least expensive and is available in a range of colors: white, blue, green etc. 

Essentially it is made up of cement and crushed marble and whilst it is relatively cheap it can be prone to staining or cracking. 


 A mixture of polymer-modified cement and quartz aggregates. 

The addition of quartz lends the surface a reflective quality and a level of visual interest beyond that of a standard plaster finish. 


Pebbles and glass beads can be used to create a wide variety of textures within the pool interior 

Small, smooth pebbles can provide a more natural look whilst glass beads lend a shimmer to the water that is not possible with standard plaster. 

Although they are more expensive these finishes are considered more durable than either plaster or quartz.


The final cost of a pool interior design and installation from our skilled Salt Lake City pool contractors will vary depending on the overall area, the type of tile or plaster finish selected and the overall complexity of a job.

Upgrading to a quartz or pebble finish can add anything from $5,000 to $20,000 to the cost of an interior finish on a standard size pool.

The cost of upgrading to tiles can vary by a lot more but this depends on the grade of tile and whether glass mosaics or ceramic tiles are being installed. 

Every project is different but as a rough guide fully tiling a pool can be at least 5 times more expensive than a plaster finish.

For this reason a lot of clients elect to use tiles selectively i.e across steps or over the shallow wet deck area to limit the overall expense.
