You said yes! You’re embarking on a bathroom renovation or construction project. We know it, this kind of project can quickly become complex, as it involves several different trades: electrical, plumbing, flooring, painting… In short, there are many steps, many purchases, and quite a few headaches.
One thing is certain: the shower is the centrepiece of a new bathroom. It can completely transform the design of your space. So it’s important to think carefully about it.
At Vitrerie BV, we see hundreds of projects every year. Trends come and go, but one thing remains: custom glass showers are always a priority in bathroom renovations.
In this article, we answer the real questions our customers ask us to help you plan your project and avoid unpleasant surprises.
Let’s get started!
What Is the Ideal Size for a Shower?
THE question we get asked most often. In fact, there is no magic size. Everything can be custom-made—we’ve even made a shower for a dog before. However, as with everything, there are still minimum requirements that must be met. Here is the list:- Minimum width: 24 inches (to fit comfortably)
- Popular standard: 36 x 36 inches
- Common variations: 30 x 36 inches
- Minimal height: 70 inches, depending on the shower head.
Our biggest project? A 10 x 10 foot (120 x 120 inch) shower in a Ville Mont-Royal residence, with multiple showerheads, built-in speakers, and coloured LED lights. When the budget allows… anything is possible, anything!
What Size Should a Doorless Shower Be?
When you remove the shower door, you’re talking about a walk-in shower or a threshold-free shower. The distinctive feature of this type of custom shower is that the floor must slope toward the drain. Without this slope, water will spread throughout the bathroom… a guaranteed tidal wave!
The minimum recommended by our experts is 60 to 72 inches (5 to 6 feet), especially if you have multiple jets.
Our main recommendation to customers who choose this type of shower is not to be cold-blooded: without a door, the steam escapes. If you tend to feel cold, you may end up shivering. Expert tip: add heated flooring to the shower. But remember, this must be planned right from the design stage.
Some customers also ask us if it is possible to add a door later on. Our answer is less encouraging: it’s difficult… in most cases, it means redoing everything.
In short, a doorless shower is very trendy and can be designed in different sizes. The important thing is to plan the project carefully from the outset (drain slope, heated floor, plumbing configuration, etc.).
What Wall Length Is Needed to Prevent Splashing?
Our answer is short and sweet: it all depends on your plumbing and the number of jets. The more there are, the more it splashes. There is no magic formula: the wall must be adapted to your configuration.
What Is the Minimum Opening Size for a Shower?
The openings depend on the type of door. Here are our recommendations:
- Pivot or hinged door: 24 inches
- Single sliding door: 48 inches
- Double corner sliding door (30 x 30): approximately 15 inches opening
What Are the Different Types of Shower Doors?
There are several options, but here are the 7 most popular ones:- Walk-in shower: open, threshold-free, with a sleek look.
- Lintel shower: with a horizontal bar at the top for added stability.
- Sliding shower: practical for saving space.
- Steam shower: hermetically sealed, hammam style.
- Full-height shower: floor-to-ceiling for a luxurious look.
- Textured glass shower: privacy and decorative style.
- Glass bathtub-shower panel: no more curtains, now it's chic.

Advice from Pierre-Hugues
The Importance of Stain-Resistant Treatment
You’ve just installed an ultra-clear glass shower? After 2-3 months, soap scum may appear and dull the transparency.
Our friendly advice: consider using a stain-resistant treatment (e.g., Diamond Fusion). Despite what you may think, glass is porous, and without protection, limescale and soap will leave permanent marks.
With this treatment, you get:
- Fewer deposits
- Easier cleaning
- Longer life
- Glass that retains its shine
