Spa and Hot Tub Buyers Guide

Choosing a hot tub or spa from Tesco direct is the ideal way to bring a new form of instant relaxation to your home. After a long day at the office, unwind in warm therapeutic waters either indoors or outside. The health benefits of soaking in a hot tub have been enjoyed for generations and now you can add a spa to your home that is easy to install, maintain and use.

Fundamental elements like dimensions, style, number of jets and functionality will influence your decision but you should also consider the installation and maintenance of your new spa. Try to envision how the unit will look in the location you have selected and then consider the number of users, proximity to an electrical supply, privacy and the view you will enjoy. As you select the right model and the place to put it, our buyers guide can help you understand what you should consider before you arrange delivery to your home.

Location of Your Hot Tub

Your new spa will be a great addition to your home - a social feature for enjoyment with friends and family. It can be fitted into an outdoor or indoor space if there are certain facilities that can be connected to the unit. The setting is important both to showcase the spa and to ensure ease of access. The tub can be sunk into a floor or decking area if there is adequate access to reach parts that need to be maintained, checked or connected.

Choose a solid, flat surface for the spa to sit on so that it has a strong base, maintaining the position of the hot tub without risk of subsidence. Check the weight of the unit and remember to include the weight of occupants before you compare to the maximum load that can be carried by the surface you have selected.

Ideal positions include concrete pads, level gravel, slabs, block paving or an adequately supported, reinforced decking area. The base location should be around one foot wider than the unit itself. Many people choose to place their spa outside so they can enjoy relaxing there during cool autumn evenings or sunny days in summer. Spas should not be placed on recently disturbed ground or an outside area that is prone to flooding.

Installing a Hot Tub

If you require your new spa model to be placed below ground or sunk into a decking area, the installation engineer will require access to all sides of the tub for servicing. It is recommended that you leave a 3 foot space all the way around and ensure that the decking boards are easily removable for any repairs to your unit.

Placing the spa in a corner position should be done so that the tub can be moved easily should an engineer require access for maintenance. Typically, it will take between 2 and 6 hours for a spa to be installed at your home. At the last stage, a hose or water supply will be connected to allow the heating element to start warming your pool to an ideal temperature.

Electrical Requirements

Your spa will require a dedicated power supply that will be tested and certified by an electrician to ensure that it is safe and provides the correct voltage. This is a standard process and an outdoor isolator switch with electrical socket no more than 3 metres away from the spa will be sufficient for the hot tub's power needs. The description of your hot tub selection will include details on the amp requirements for your unit, which can range from 32 amp to 40 or 50 amp.

Getting Your Spa Delivered

Before your spa arrives it's a good idea to walk the route that the unit will need to take to reach the set-up point. The tub will arrive on a trolley, so it's important to measure your home or garden space accurately and clear a path, ensuring there are no items blocking delivery. If the tub cannot be wheeled through to the right position then a crane may be necessary, which can make your spa a little more expensive.

Remove any debris from the site itself and ensure the base is flat and cleared. It is sensible to check the area with a spirit level or similar tool to ensure it is flat before you begin. Walk around your preferred setting to ensure that there is a 3 foot gap around the space for the tub and that items like sheds, greenhouses, patio furniture or fence panels will not hinder a smooth installation.

Hot Tub Maintenance

Some simple maintenance of your hot tub can ensure that you will enjoy your unit effectively and safely. A plumber or electrician should be consulted if there are any problems to resolve with your spa after installation but regular maintenance checks will ensure that your tub can function for a long time. Your spa should be fully inspected and serviced once a year to keep performance smooth.

You should also remove spa pillows from the water when the spa is not in use to ensure they remain in peak condition (pillows that break down due to being left in the spa are not covered by the manufacturers warranty). Water level should be maintained just below the pillows and above the highest jets (above the highest jets on coyote models). You shouldn't hear slurping or surging of air as the water is circulating through the filter, this could cause an air lock at the pump

Other straightforward steps that should be taken include:

Draining Your Tub

Your hot tub should be fully drained and re-filled at least every 12 weeks but you're draining routine can range from 8-12 weeks depending on how often you take a dip in the spa. When refilling the spa, the hose can be placed either in the bottom of the unit or in the filter bucket. This will allow the spa to fill from the lowest points which helps prevent air locks at the pumps. When your spa has heated to a minimum of 32 degrees, bring the chlorine/bromine range to 20ppm and circulate the water for around two hours. This will effectively treat the water and remove any bacteria built up in the lines. If you have an air blower, run this for the first 20 minutes to reduce aerosol formation.


Your spa should be tested daily to check the pH levels and alkalinity of the water. The readings you should be seeing are: Chlorine/bromine 3-5ppm, PH between 7.2 and 7.6 and Alkalinity between 80 and 120ppm. Adjust levels after testing to make sure the water is ready for you to enjoy a soak.


If your model of spa includes disposable filters then these should be changed every 3 - 4 months depending on how often you use the pool. It is essential that short pleated filters and rescue bags are also checked and cleaned on a regular cycle - we recommend every week, during periods of heavy pool use, increasing to every two weeks when you take a dip in the hot tub more occasionally.

Ideally your spa should be serviced once a year to maintain it to its optimum performance. You can speak to the sales team on the service packages available. Overall, if you clean and maintain your spa, it should be an excellent addition to your home, providing a place to relax and unwind, or spend time with friends and relations.
