DIY projects can be immensely satisfying and cost-effective. However, when it comes to hot tubs, attempting DIY hot tub fixes can often do more harm than good. These complex systems require specialised knowledge and careful maintenance to function properly.

In this article, we will explore five DIY hot tub fixes that you should steer well clear of to avoid potential disasters. From electrical hazards to structural compromises, these risky repairs are best left to the professionals.


  • Electrical repairs on hot tubs should always be handled by licensed professionals to avoid shocks, fires, and further damage. 
  • Using DIY sealants or attempting to repair hot tub shells yourself can compromise structural integrity and lead to leaks. 
  • Replacing hot tub components like pumps and heaters requires precise installation to prevent water damage, gas leaks, and fire hazards. 
  • Improper cleaning methods, draining, or modifications can severely damage hot tub materials and pose safety risks.

DIY hot tub electrical repairs

Working with electricity is an inherent risk in any project involving DIY hot tub repairs. A single misstep could result in a severe electric shock or even start an electrical fire. That’s why it’s crucial to leave any electrical repairs to a qualified, licensed electrician.

Attempting to replace the hot tub’s control panel, for instance, is an ill-advised move. These panels are intricate systems that control various functions, and improper installation could lead to short circuits, shocks or further damage. According to a report by the Electrical Safety Foundation, over 50,000 home electrical fires occur annually, many caused by DIY errors.

Rewiring a hot tub is another task best avoided by amateurs. Hot tubs have complex wiring systems, and any mistakes could create dangerous shorts or overloaded circuits, increasing the risk of fires. A startling 68% of residential electrical fires involve wiring, per the National Fire Protection Association.

Repairing cracks or leaks

Cracks or leaks in a hot tub’s shell or plumbing must be addressed promptly to prevent water damage, mould growth, and other costly issues. However, attempting DIY repairs with sealants or epoxy is a temporary fix that often leads to further cracking or leaking down the line.

Even more risky is trying to repair the acrylic or fibreglass shells yourself. These materials require specialised techniques and tools to repair properly. Improper repairs can compromise the structural integrity of the hot tub, potentially causing catastrophic failures. 

Replacing the pump or heater

The pump and heater are crucial components that keep your hot tub functional and comfortable. Attempting to replace these intricate parts yourself is a recipe for disaster if not done correctly.

Installing a new pump involves complex plumbing and electrical connections that require precise calibration. Even minor leaks can cause significant water damage over time. Replacing the heater is equally risky for DIYers. Improper ventilation or installation could lead to fire hazards or carbon monoxide poisoning.

Cleaning and maintaining the hot tub

Proper cleaning and maintenance are essential for keeping your hot tub in top condition. However, using household cleaners or DIY cleaning solutions can be incredibly damaging to the tub’s materials and potentially cause skin irritation or respiratory issues.

Draining and refilling the hot tub improperly can also spell disaster. Failing to follow the manufacturer’s guidelines could result in water damage, electrical shorts, or other costly issues. Make sure to use only clinically tested and proven cleaners for your hot tub.

Modifying the hot tub structure

Many hot tub owners are tempted to modify the structure by adding or removing jets, or changing the shape or size. However, these modifications can severely compromise the structural integrity of the hot tub, leading to cracks, leaks or even complete failure.

Adding or removing jets requires intricate plumbing and electrical work that should only be handled by professionals.

Altering the size or shape of the hot tub shell is an even riskier endeavour. The materials are designed to withstand specific stresses, and any modifications could weaken the structure.
