Top 5 Features to Look for in a Quality Hot Tub

When it comes to choosing a hot tub, not all spas are created equal. From comfort to construction, the right hot tub can transform your space into a daily retreat — and the wrong one can lead to regret and repair bills. Whether you're a first-time buyer or ready to upgrade, here are the five essential features to look for in a quality hot tub — and why PDC Spas stands apart in every category.

1. Reliable Insulation and Energy Efficiency

Your hot tub should work efficiently year-round — without causing a spike in your energy bill. Look for models with high-quality insulation that retains heat and reduces operating costs.

What to look for:

  • Full-foam or reflective thermal insulation

  • Tight-fitting cover to lock in heat

  • Energy-efficient pumps and plumbing

Why PDC:
All PDC Spas hot tubs are engineered with energy savings in mind. Our TemperLok system minimizes heat loss, while our custom-fit covers add an extra layer of thermal protection. This means your spa stays warm — and your costs stay low.

2. Durable Construction and Materials

Quality starts at the core. The best hot tubs are built with long-lasting materials that resist warping, cracking, or fading — even with daily use and exposure to the elements.

What to look for:

  • Weather-resistant cabinetry

  • Reinforced shell design

  • American-made materials

Why PDC:
Our hot tubs are proudly made in the USA, using premium Lucite® acrylic shells and a precision-engineered frame structure. The Black Accenture™ cabinetry isn’t just sleek — it’s built to withstand changing weather without compromising on style.

3. Powerful and Adjustable Hydrotherapy Jets

A hot tub isn’t just for soaking — it’s for healing. A well-designed spa includes jets that target key muscle groups with both power and precision.

What to look for:

  • Variety of jet styles and placements

  • Adjustable pressure settings

  • A balanced mix of high- and low-impact jets

Why PDC:
Our Reflections™ Jetting System is engineered for optimal relief, offering a unique blend of massage options. Whether you’re easing tension in your back or refreshing tired feet, you’ll find the perfect setting to suit your needs.

4. User-Friendly Controls

Your spa experience should be simple — not stressful. Intuitive, reliable controls let you adjust temperature, lights, and jets with ease.

What to look for:

  • Touchscreen or backlit controls

  • Durable, waterproof interface

  • Easy-to-read display

Why PDC:
With our ProView™ Control system, everything is right at your fingertips. Designed for seamless operation, our controls are easy to navigate — even in low light or cold weather.

5. Built-In Water Purification System

Clear, clean water is a must — without constant hassle. A high-quality spa should include advanced water treatment systems to reduce the need for harsh chemicals and frequent maintenance.

What to look for:

  • Ozone or UV water purification

  • Filtration systems that run quietly and efficiently

  • Easy filter access and replacement

Why PDC:
Every model is equipped with our EverPure™ Ozone System, which naturally neutralizes bacteria and reduces chemical usage. It’s cleaner water with less effort — so you can spend more time relaxing.
