Custom Shower Enclosure: when it is worth it, how to measure it and how much it costs

Standard shower enclosures and screens cover most bathrooms, and many can be adjusted within a few centimetres. A custom enclosure is worth it when the space is atypical – sloping ceiling, niche of unusual width, uneven walls or large frameless glass. We will show when a standard with adjustment is sufficient, how to measure a custom enclosure and for price comparison of standard screens and trays that can be adjusted.

A custom shower enclosure sounds luxurious, but sometimes it is the only solution that fits in the bathroom. At other times, a standard screen with an adjustable profile is sufficient, saving you time and money. An overview of dimensions and types of enclosures can be found in the article Dimensions of Shower Enclosures, with a comparison of trays and without in the article Shower Enclosure with Tray or Without.

When is a standard enclosure sufficient

• The space corresponds to standard dimensions and the walls are straight and at right angles.
• The difference is a few centimetres – many screens have an adjustable profile. On vkupelni.sk, for example, the walk-in screen MASTER F1 is available in the range of 70 to 100 cm or the bath screen ROYAL VF1 in the range of 70 to 80 cm.
• The height is standard – without slope and low ceiling above the shower.
• The niche has a standard width – standard sizes with adjustable range are manufactured for shower doors into niches.

When is a custom enclosure worth it

In the attic, the space for standing also matters – how to plan a shower under the slope is described in the article Bathroom in the attic.

custom shower tray or fall in floor tiles

For a custom enclosure, the floor must also be addressed. There are two options: a tray that can be adjusted in size, or a level-access shower with a fall in the floor tiles and a drain. Cast marble shower trays can often be shortened to size. For example, on vkupelni.sk, there are FLEXIA trays with adjustable size options (prices including VAT as of November 2026):

You can find more in the category Custom shower trays. How to build a level-access shower with a brick wall is described in the article Brick shower enclosure.

Glass and profiles

• Glass thickness – 6 mm is common for standard doors, 8 mm for walk-in and frameless enclosures. Large custom glass requires a stabilizing rod or a fixed mounting profile.
• Glass treatment – a protective layer against limescale makes maintenance easier, more in the article Protective treatments for shower glass.
• Profiles and fittings – chrome, black or brushed metal. For a custom enclosure, you choose them together with the glass.
• Mounting – glass is mounted to the wall according to the manufacturer. Reinforcements must be prepared in drywall before tiling.

Measurement and procedure

1. Decide on the type – door, walk-in, niche enclosure, with tray or without.
2. Prepare the plumbing, waterproofing, and reinforcements for mounting the glass.
3. Complete the wall and floor tiles including grouting.
4. Measurement – the manufacturer or glazier measures the space only on finished wall tiles. For slopes, they also measure the angle and heights.
5. Production – check the delivery time when ordering and plan the installation date accordingly.
6. Installation and silicone – after sealing, adhere to the time specified by the silicone manufacturer.

How much it costs: standard for comparison

Custom enclosures are not available in the e-shop – the price will be calculated by the manufacturer or glazier based on dimensions, thickness, and glass treatment and fittings. For comparison, examples of standard screens from vkupelni.sk (including VAT as of November 2026, excluding installation):

More models can be found in the category Walk-in screens. If a standard screen fits after adjustment, it is a quicker and cheaper option. How to decide between a walk-in and an enclosure with doors is compared in the article Walk-in or shower enclosure.

How to decide: standard or custom

1. Measure the space in multiple places – width at the bottom, middle, and top. If the dimensions differ by more than what the profile can compensate for, the standard will not fit.
2. Compare with the adjustment range of standard screens and doors, which the manufacturer specifies for each model.
3. Check the height – for slopes or low ceilings, find out if the glass and head can fit with space for standing.
4. Decide on the floor – tray with adjustable size, or level-access shower with fall and drain.
5. Request a quote for a custom enclosure and compare it with the standard including any wall adjustments.

Common mistakes

• Measurement before tiling – after tiling, the dimension changes and the glass does not fit.
• Missing reinforcements in drywall for mounting the glass.
• Custom glass where an adjustable profile is sufficient – unnecessarily longer wait and higher price.
• Forgotten fall in a level-access shower – water collects by the glass.
• Too thin glass for a large walk-in wall without stabilization.
