Toughest and Most Durable Hot Tub Shells Available

Introduction

What Coast Spas will never teach you is how to fix a crack in your Hot Tub. That’s because you will never need to fix one. In a competitive world where bigger profit margins are always chased after by cutting corners, Coast Spas come in last when it comes to compromising quality and durability. There’s a reason why they trademarked the phrase, “Build to Last®”, that’s because they mean it.

Our Shells

The shell is the most important part of a hot tub, it can never be replaced. It needs to endure the travel from your local dealership to your home, hold over 1500 liters of water, and has to take the weight load of several bathers at a time. For over 20 years Coast Spas has heard its share of horror stories of tubs falling off trucks at over 40 miles an hour and still being intact…but we won’t get into that.

A hot tub is one of the most important investments you will make in your lifetime. It needs to stand the test of time. It’s a social oasis where your friends and family connections, it soothes your aching muscles, it provides tranquility from today’s hustle and bustle.

Coast Spas® has partnered with Owens Corning® to deliver the toughest and most durable hot tub shells available. Your hot tub starts its life as a sheet of premium acrylic. It is then heated and vacuum-formed to take on the shape of a hot tub, at this point the acrylic is fragile and flexible. The acrylic shell is then moved to be reinforced using high-grade Owens Corning® fiberglass. A team of specialists start by applying several layers of fiberglass to the shell, then use rollers to compress those layers together. Steel angle iron is then placed onto those first compressed layers for additional support in specific structural areas.

Additional layers of Owens Corning® fiberglass are then added (up to 12 layers or more are typical for an average-size Coast Spas Model) and compressed again, by hand, to complete the shell reinforcement.

The acrylic is reinforced using around to 12 layers (average for a Coast Spa), of Owen’s Corning high-grade fibreglass. This is hand rolled on by a team of specialists and compressed to form a strong, structured backing on the shell. Steel angle iron is then inserted into load-bearing areas before additional fibreglass layers are added.  Multiple Layers of Premium Owen Corning® Fiberglass with Steel Reinforcement

Why Does Shell Strength Matter?

Your Hot Tub or Swim Spa shell is not just one of the most expensive components of your spa, but also the only piece that can never be replaced. If your hot tub cracks, there is no real avenue for structural repair – and your hot tub will no longer be able to be used. Your spa shell is responsible for containing large volumes of water that has a significant amount of weight. This weight is constantly applying immense pressure to your shell and its integrity has to hold even when faced with environmental fluctuations in temperature and humidity. Ensure your next hot tub has the strength and durability of multi-layer Owens Corning Fiberglass and steel reinforcement.
