Once you have decided to add a sauna to your home, the next big question is how to build it: a ready-made pre-built sauna, or a fully custom design? Both deliver a wonderful sauna experience, but they suit different budgets, timelines and spaces. This guide compares pre-built and custom saunas, weighing the pros and cons of each, so you can choose the option that best fits your home, goals and budget.
Quick summary: A pre-built sauna is factory-made in modular sections for fast, lower-cost, high-quality installation, ideal if you want a quick, reliable result. A custom sauna is designed from scratch to fit any space and specification, perfect for unique layouts and premium, fully tailored builds. Both can be beautiful and long-lasting.
What Is a Pre-Built Sauna?
A pre-built (or modular) sauna is manufactured in a factory as ready-to-assemble sections, then delivered and installed in your home. Because it is engineered in controlled conditions, quality is consistent and installation is fast. Pre-built saunas come in a range of standard sizes and designs, offering an efficient route to a premium sauna. Explore our pre-built sauna rooms.
What Is a Custom Sauna?
A custom sauna is designed and built specifically for your space, from the dimensions and layout to the timber, glass, lighting and finishes. It can fit awkward areas, match your interior design exactly, and incorporate premium or unusual features. The trade-off is a higher cost and longer timeline. For planning a bespoke build, see our home sauna design guide.
Pre-Built Sauna: Pros and Cons
- Pros: faster installation, lower cost, consistent factory quality, easier to relocate, less on-site disruption.
- Cons: limited to standard sizes and designs, less flexibility for unusual spaces or bespoke features.
Custom Sauna: Pros and Cons
- Pros: fits any space, fully tailored design and materials, ideal for premium and unique builds, maximises awkward areas.
- Cons: higher cost, longer design and build timeline, more on-site work.

Frequently Asked Questions
What is a pre-built sauna?
A pre-built, or modular, sauna is manufactured in a factory as ready-to-assemble sections, then delivered and installed in your home. This gives consistent quality and fast installation, in a range of standard sizes and designs.
Is a pre-built or custom sauna better?
Neither is universally better. Pre-built saunas offer speed, value and consistent quality for standard spaces, while custom saunas provide full design freedom for unique layouts and premium builds. The best choice depends on your budget, timeline and space.
Are pre-built saunas good quality?
Yes. Because they are engineered in controlled factory conditions, pre-built saunas offer reliable, consistent quality. With premium materials and a properly sized heater, a pre-built sauna can be every bit as satisfying as a custom build.
How much cheaper is a pre-built sauna?
Pre-built saunas are generally more affordable than custom builds because they use standard designs and require less on-site labour. The exact saving depends on size and specification, so it is best to compare quotes for both options for your space.
Can a pre-built sauna be moved?
Often yes. Because pre-built saunas are assembled from modular sections, many can be disassembled and relocated, making them a flexible choice if you may move home or want to reposition the sauna later.
How long does a pre-built sauna take to install?
Pre-built saunas install much faster than custom builds, often within a few days once delivered, since the sections are made in advance. Custom saunas take longer due to bespoke design and on-site construction.
