The truth about owning a swim spa or hot tub: FAQs

Your big questions answered:

What should I consider when choosing a location for my hot tub?

Location is key! Consider these factors:

• Proximity to the house: Do you want it close for easy access or in a more secluded spot?
• Path to the hot tub: Ensure a non-slip surface to avoid tracking dirt and contaminants into the water.
• Overhead obstructions: Avoid power lines and trees to minimize debris.
• Privacy: Consider screening or fencing if neighbors are close.
• View: If you enjoy stargazing, ensure an unobstructed view of the sky.
• Indoor installations: Account for ventilation, drainage, overspill, and maintenance access.

How do I safely transport and install my hot tub?

Hot tubs are heavy and require careful handling. It’s highly recommended to use the delivery and installation services offered by reputable retailers. They have the experience, tools, and insurance to ensure a safe and damage-free process. If you choose to install it yourself:

• Measure carefully: Account for the hot tub’s dimensions on its side, including the trolley height and packaging.
• Clear the path: Remove obstacles like overhanging eaves, branches, or fence sections.
• Protect the ground: Use scaffolding boards to protect delicate surfaces like lawns or gravel.
• Enlist help: Get strong helpers for lowering the hot tub from the trolley.
• Consider a crane: For restricted access, utilize the services of a professional crane company.

What type of foundation does my hot tub need?

Your hot tub needs a firm, level base capable of supporting its weight, water, and bathers without shifting.

• Concrete pad: A 4″ (100mm) deep reinforced concrete pad is the most common and recommended foundation.
• Decking: Ensure the sub-structure is strong enough to handle the weight. Be mindful of noise and vibration transmission.
• Gravel: Compact the gravel thoroughly to create a stable base.

What are the electrical requirements for installing a hot tub?

Hot tub electrical installations must adhere to strict regulations.

• Dedicated circuit: The hot tub must be connected to its own correctly sized fused spur wired directly back to the consumer unit.
• SWA cable: Use Steel Wired Armoured (SWA) cable for the connection.
• RCD protection: The circuit must be protected by its own Residual Current Device (RCD).
• Competent electrician: All electrical work must be carried out and signed off by a qualified electrician according to Part P of Building Regulations.

How do I maintain the water clarity in my hot tub?

Cloudy hot tub water is a common issue often caused by bather-introduced contaminants. To prevent and treat cloudy water:

• Maintain proper sanitation: Test and adjust sanitiser (chlorine or bromine) levels daily.
• Regularly oxidise impurities: Shock dose your hot tub weekly and after heavy use to break down organic matter.
• Clean filters regularly: Rinse filters frequently and use a filter cleaning product monthly. Replace filters every 12 months (or 24 months if rotating two sets).
• Use a clarifier: Clarifiers bind tiny particles together, making them easier for the filter to remove.

What causes hot tub foam and how can I prevent it?

Foam is caused by a build-up of products and Total Dissolved Solids (TDS) in the water. To minimize foam:

• Shower before use: Rinse off any lotions, deodorants, or cosmetics.
• Rinse bathing suits: Avoid washing them with detergents; rinse with clean water after each use.
• Use quality chemicals: Stick to reputable brands recommended by the manufacturer.
• Weekly shock treatment: Break down TDS and organic matter with a weekly shock dose.

Why and when should I shock my hot tub?

Shocking your hot tub is crucial for maintaining water hygiene and safety. Shock treatment:

• Removes biological waste: Breaks down unfilterable contaminants introduced by bathers.
• Eradicates resistant bacteria: Kills bacteria that may have developed resistance to the regular sanitizer.
• Reactivates sanitiser: Removes chloramines or bromamines, restoring the sanitiser’s effectiveness.

Shock your hot tub at least once a week and after heavy use.

What are some tips for hosting a safe and enjoyable hot tub party?

Hot tub parties can be a great way to entertain, but safety and water hygiene should be top priorities.

• Limit soaking time: Encourage guests to take breaks after 15 minutes.
• Hydrate with non-alcoholic drinks: Provide plenty of water or non-alcoholic beverages.
• Supervise children: Never leave children unattended near or in the hot tub.
• Manage bather load: Avoid overcrowding to maintain water quality. Use the hot tub in shifts if necessary.
• Establish rules: Communicate guidelines for showering, no jumping, and no glass containers.
• Maintain water quality: Test and adjust sanitizer and pH levels after each shift.
