If you had to choose between a swimming pool and a hot tub or spa, which would it be? Most people would probably go for the hot tub. They are less expensive to install or buy, take up less space and can be enjoyed throughout the year. Plus, their smaller size makes them easier to clean and maintain. While you will still need to enlist the services of a landscape professional, general contractor, or pool builder, the hot tub project should take less time than a pool. 

A spa or hot tub can grow to include a deck surround, built-in seating, privacy walls, and other features. You might want to add mosaic glass tiles or surround it with cut stone or flagstone. 

Styles and designs should reflect the architecture and materials of your home and landscape. Ready for some inspiration? Enjoy these fabulous and vastly different hot tubs and spas.

    Considerations Before Building a Spa

    Spas range from purchased models that are basic or include all the bells and whistles, inflatable models for the budget-minded, custom-built in-ground designs that are like small pool projects, and spools, which are a hybrid pool and spa. Before taking the plunge, do your research, including:

    • Finding out how much the type you want will cost
    • Getting recommendations from neighbors and friends for pool builders to use and to avoid
    • Figuring out how much space it will take and where it will be located in your yard
    • Identifying the costs and availability of materials
    • Building permits and zoning laws
    • Factors like plumbing and electricity

    Like a swimming pool, the pit or hole for an in-ground spa will need to be excavated by a machine, which means the equipment must access your yard. Reinforcing rebar will be built to create the shape of the spa along with steps and benches. Plumbing, which includes drains and inlets for those therapeutic hydro-jets, will need to be installed, as will electrical wiring. After this, gunite or shotcrete will be sprayed on the rebar to create a nice, tight shell. Then it will be smoothed with a trowel and cured for a few weeks. Once it's dry, either plaster or tile will be applied to the surface. And this is just the spa part of the project.

Lima & Associates made this luxurious spa the focal point of the outdoor space. Resembling a beautiful square pond with a weir that is a fountain feature, the spa features a back wall made of glass tile and a face of travertine.
