What to Look for When Buying Hot Tub Replacement Parts

What to Look for When Buying Hot Tub Replacement Parts

When your hot tub isn’t performing at its best, it may be time to replace a part — whether it’s a faulty pump, a cracked heater, or a worn-out filter. But buying hot tub replacement parts can be tricky if you don’t know what to look for. This guide will walk you through how to choose the right spa parts, so you avoid costly mistakes and keep your hot tub in top condition.

 1. Know Your Hot Tub’s Make and Model

The first step is to identify your spa’s brand, model, and year. Spa parts are often specific to certain models. Check your owner’s manual or look for a label on the control box or back panel.

2. Match the Part Number (If Available)

Whenever possible, look for the part number printed on the old component. This is especially useful for:

  • Spa pumps

  • Control boards

  • Heater elements

  • Sensors

If you have it, use it! It’s the fastest way to guarantee a perfect match.

3. Choose OEM or High-Quality Aftermarket Parts

There are two reliable types of parts:

  • OEM (Original Equipment Manufacturer): Made by your spa’s brand; exact fit.

  • Aftermarket: Often more affordable and just as durable — but only if purchased from a trusted source.

We carry both, and we only stock quality parts we’d use in our own hot tubs.

4. Be Cautious with Generic or “Universal” Parts

Not all spa parts are created equal. Avoid using generic versions of critical components like:

  • Circuit boards

  • Pressure switches

  • Spa pumps

A wrong fit could cause major issues — even total spa failure.

5. Know the Installation Requirements

Before buying a part, check the:

  • Electrical specs (voltage, amps)

  • Plumbing size (2" or 1.5" fittings?)

  • Compatibility with your control system

Some parts are easy DIY installs. Others may require an experienced technician.

6. Shop with a Trusted Spa Parts Dealer

Not all retailers are the same. Here’s what to look for:

  • Verified reviews

  • Expert support team

  • Return & warranty policies

  • Fast shipping
