Reinforced 8mm Baths

All the baths we offer have to be of exceptional quality due to the amount of jets we like to fit in them and anything flimsy we don't want to touch. Solid bathtubs are so much easier to deal with when it comes to adding whirlpool systems. We fit the best systems and thus want to supply on the best whirlpool baths out there.

Do you sell reinforced baths?

Yes. The tubs you’ll see on site will usually have an 8mm reinforced sheet for added protection. This helps do two important things:

  • provide great heat retention
  • provide added rigidity to the tub

What is the average thickness of a bath?

Most baths in the UK will be 5mm thick. Some lightweight models can be as thin as 3.2mm, especially if it’s a one-sheet metal bath.

If you are looking for a bath that has good heat retention, a reinforced 8mm bath is a good choice.

What is Carronite / Armatec / Aquamaxx?

These are three terms that all describe the same product. 

One of the most popular brands we sell is Carron whirlpool baths. The company created its own reinforced material (Carronite) a few years ago, and it was seen as a pioneering finish for bathtubs.

Since then other manufacturers have followed suit producing their own similar finish that adheres to the 8mm standard. 

Aquaestil uses the term AQUAMAXX. They describe it as a durable, hi-tech super reinforcement coating that provides cast iron strength and extra thermal insulation. 

Armatec is the name we use for our range of Luna whirlpool baths.

How are whirlpool baths reinforced?



The process itself is the action of taking the existing acrylic bath, then adding an extra triple layer of reinforcement. 

What is the reinforced layer made from?

The reinforced layer is made up of layers of fibreglass, resin and a special hardening composite. The result is a much more rigid and strong bathtub, resulting in a more solid and comfortable experience when bathing.

It is worth noting that Carron also do panels with the special Carronite reinforced finish. These can be found in the accessories section.

What are the benefits of having extra reinforcement?

There are several reasons you might want to have a reinforced layer. They include:

  • An amazingly strong, rigid bathtub that will never flex or bend.
  • Greater thermal retention properties than a standard acrylic or steel bath.
  • Extra layers of insulation.
  • The bathwater will stay warmer for longer up to 30 minutes in some tests.
  • British made quality and recommended by professionals.
  • 30-year warranty.
  • Unique installation system ensuring the weight is spread evenly.


How can I keep a bath warm for as long as possible?

For the majority of whirlpool baths we sell on-site, you also have the chance to have an inline heater installed. This is a heater around the tub that turns on when you fill the bath. It helps keep the water at the same temperature throughout your soak, so you never have to worry about “topping up” the bath every once in a while.

What shape do reinforced 8mm baths come in?

Pretty much any shape and style of bath can be reinforced, including:

  • D-Shaped
  • Corner
  • Freestanding
  • J-Shaped
  • Extra-Deep
  • Inset

Do freestanding baths need extra reinforcement?

The protective layer, depending on which make you buy, should do the job of reinforcing a freestanding bath properly.

If you’re someone who likes to have the temperature at a certain level, having an inline heater installed may be worthwhile.

  • 1. What is Carronite / Armatec / Aquamaxx?

    These are 3 terms for in effect the same thing. Carron bathrooms pioneered Carronite a few years ago and other manufactures have followed suit producing their own similar finish to rival. Aquaestil use the term AQUAMAXX. They describe it as a durable, hi-tech super reinforcement coating that provides cast iron strength and extra thermal insulation. Armatec is the name we use, for the same process being applied to our Luna range of baths.

    The process itself is the action of taking the existing acrylic bath then adding an extra triple layer of reinforcement. This triple layer of reinforcement is made up of layers of fiberglass, resin and a special hardening composite. The end result is a much more rigid and strong bath tub, resulting in a more solid and comfortable experience when bathing or showering.

    It is worth noting that Carron also do panels with the special Carronite reinforced finish these can be found in the accessories section.

  • 2. What are the benefits of the extra reinforcement?

    The benefits can be broken into the following points:

  • An amazingly strong, rigid bathtub that will never flex or bend.
  • Greater thermo retention properties, than a standard acrylic or steel bath.
  • Extra layers of insulation.
  • The bath water will stay warmer for longer up to 30 minutes in some tests.
  • British made quality and recommended by professionals.
  • 30 year warranty.
  • Unique installation system ensuring the weight is spread evenly.

  • Some people refer to these special finishes as the best alternative to a steel bath but don't take our words for it, read this handy thread we found on line to help you decide if its worth putting those extra pounds in to a reinforced finish.
