Steam Showers.
Engineered to last.

Most people only get one shot at a steam shower. We make sure it is right. Pro-Grade Plumbing & Gas guides you through every stage, from the first conversation to the day you step in and use it. You will always know exactly where your project stands and what comes next.

Our Preferred System & Beyond

Mr Steam is our recommendation.
We will install whatever you specify.

When someone asks us what we would put in our own home, the answer is Mr Steam. It is not just about the product itself. It is about the quality of the support, the availability of parts, and the way the whole experience is backed up over time. That is what makes it the system we recommend on every project where the client is open to our advice.

If your project already has a different brand specified, whether that is Kohler, Steamist, Tylo, or something else entirely, you are in exactly the right hands. We bring the same care and the same standard of workmanship to every installation. The brand is your decision. The quality of the work is always ours.

Selected Projects

Work we are proud of.

Every project here was built in close collaboration with the people who care about it most. We took the time to understand the space, listened carefully to what was needed, and stayed involved right through to the final handover.

Vaucluse New Build

Large format porcelain with a concealed Mr Steam outlet and flush linear drain. We were engaged early by a local high end architectural firm, and that early involvement made all the difference to how cleanly the final result came together.

Technical Expertise

What we take care of so you do not have to

Steam shower installation involves a set of decisions that need to be made early and made well. When a specialist is involved from the start, those decisions protect your project and your investment. When they are not, problems tend to surface long after the tiles are down and the costs of fixing them are already significant. We are here to make sure that does not happen to you.

01

Sizing the System

We assess every project individually to determine the right generator size. This single decision shapes the entire experience you end up with, so we take it seriously and we get it right before anything else moves forward.

02

Steam Line Routing and Insulation

We plan the route from generator to enclosure carefully, because once the walls are closed up there is no going back. You can trust that this is handled correctly from the start, which means no costly surprises later.

03

Managing Vapour Properly

Steam environments behave differently to standard showers. We coordinate with the other trades at design stage so that vapour is managed correctly across the whole build. This is how your investment stays protected.

04

Enclosure Shape and Layout

We review the geometry of the enclosure early and flag anything that could affect how the system performs. Catching these things at design stage means your designer's vision stays intact and the system works as it should.

05

Generator Placement and Access

We plan the generator location with long term access in mind. That means servicing stays straightforward for the life of the installation and you are never faced with the cost of opening up finished work just to get to a component.

06

Controls and Trade Coordination

We manage the interface between the steam controls and every other trade involved. You get a system that commissions cleanly, performs as intended, and does not leave anyone on the project chasing up loose ends.

What Can Go Wrong

What a poor installation actually costs you

Most steam shower problems do not show themselves during the build. They show up later, and by then they are expensive and disruptive to deal with. We want you to go into your project with a clear picture of what is at stake and the confidence that comes from having the right people involved.

A system that never delivers

A steam shower that falls short of what was specified and paid for is a difficult conversation for everyone involved. The client is disappointed, the builder is fielding complaints, and the source of the problem is often buried in decisions made long before handover.

We look at the full picture before anything is specified or any work begins. You can count on that.

Defects that appear after handover

The most disruptive failures tend to surface 12 to 18 months after the project is complete. Tracing them back to their cause is complex, time consuming, and costly for everyone. Getting the installation right is the only reliable way to avoid that situation entirely.

Our involvement from design stage is specifically aimed at preventing these outcomes. We stay with you through the whole process.

Moisture damage inside the structure

Steam places demands on a building that go well beyond what a standard wet area creates. When those demands are not properly managed across all trades, moisture can work its way into walls and substrates and remain invisible until the damage is already serious.

We coordinate across all trades at design stage so that nothing falls through the gaps. Your project is in good hands.

Performance issues blamed on the product

When a premium system underperforms, the product is often the first thing to be questioned, even when the installation is where the problem actually lies. That leads to warranty disputes, frustrated clients, and damaged relationships across the project team.

A well installed system performs as the manufacturer intends. We make sure the installation is never the weak link in your project.

A system that is hard to service

Steam generators need regular maintenance. When the installation has not been thought through properly, servicing becomes a major undertaking or simply does not happen. A neglected generator will eventually fail, and by then the cost of dealing with it is far greater than it needed to be.

We plan for long term serviceability from the start. You will not be left wondering how to look after what we have built.

A significant remediation bill

When a steam installation fails in a meaningful way, putting it right is rarely a small job. Tiling, cabinetry, substrates, and mechanical work all have to come back. On a luxury project, the cost of remediation can be comparable to the original build cost.

Getting it right the first time, with the right people alongside you from the start, is what we are here for.
For the Trade

Built to work alongside architects, designers and builders

We understand that your reputation is on the line on every project, just as ours is. We treat the relationship with that respect. We show up when we say we will, we communicate clearly throughout, and we give you the technical input you need early enough to actually use it. Working with us should make your job easier, not harder.

Early involvement at design stage

We review your drawings and raise any steam specific considerations before the trades start. That kind of early input protects your design intent and saves everyone from costly variations later.

Scheduling that fits your programme

We integrate into your build schedule at each stage, rough in, fit off, and commissioning, and we coordinate with the other trades on your timeline. You will not be waiting on us.

One person, start to finish

You deal with the same person throughout. There are no handoffs, no miscommunications passed down a chain. Just a straightforward working relationship with someone who knows your project inside out.

Complete compliance documentation at handover

Certificate of Compliance, as installed drawings, and the Mr Steam commissioning report are all provided at handover without you needing to ask. Your client gets confidence, and you get a clean close out.

Already own your home? We can add a steam shower to an existing bathroom too.

Not every steam shower starts with a new build. If you have an existing bathroom you would love to transform, we work with homeowners directly to assess what is possible and manage the whole process for you. Same specialist care, same standard of finish.
