Glass block shower wall cost

Glass brick walls work well in shower areas as they’re waterproof, noise-resistant and easy to clean. But how much does a glass brick shower wall cost?:

• The typical cost for a glass block shower that’s made from individual glass blocks and built in a curve is between £1,000 and £2,200

• It’s likely to take around one to two days to install

Glass block window cost

Installing a small glass block window could cost as little as between £300 and £400 (supply & install).

Glass block windows are popular in bathrooms, basements and side-return extensions where privacy matters more than ventilation. They:

• Let light through without a clear line of sight

• Requires no frame or sill

• Are very low maintenance

That said, the obvious downside to window blocks is that they can't be opened.

What affects the cost of a glass block wall?

The total glass brick wall cost depends on a number of factors. Here are some of the main ones:

• Size: The bigger the glass block wall, the more expensive it will be

• Type: Glass block walls can be purchased as individual blocks or as a pre-fabricated wall. Individual blocks laid in mortar give the most flexibility, but pre-fabricated panels are faster to fit and often cheaper to install

• Assembly type: If you’re installing individual blocks, you’ll have to choose how to hold the blocks together. Mortar is the cheapest, followed by silicone, and vinyl spacers are the priciest

• Material: Clear glass is the cheapest option, but you could splash out on coloured glass or (most expensive) acrylic

• Style: Similarly, you could opt for effects such as frosted, wavy or diamond-patterned glass. These will cost more than clear glass

• Supplier: Suppliers range in price a lot depending on their speciality. Some offer noise filtering blocks or blocks with enhanced thermal efficiency

Other glass block wall costs to watch out for

• Reinforcement bars and spacers: Sometimes steel rods and spacers are needed for structural glass block walls, which will be an add-on cost

• Location: If you're based in London or the South East, labour costs may be higher due to demand

• VAT: Always check whether VAT is included in the price you're given

• Removal of existing structures: Taking out an old window, wall section, or damaged glass blocks may be an additional cost

• Involves shower enclosures where the waterproof seal matters (mistakes with mortar or silicone in a wet area can be expensive to fix)

Glass block wall cost FAQs

Are glass blocks good for showers?

Yes, glass blocks are a great option for shower. They're waterproof, easy to clean, and naturally light-diffusing, making them a practical and stylish choice for shower enclosures. They're more robust than shower screens and don't require a track or frame.

How much does a glass block wall cost?

A glass block partition wall (10×10 blocks) typically costs between £700 and £1,800 all in. A smaller glass block window job runs between £300 and £400 (supply & fit). A glass block shower wall costs between £1,000 and £2,200 (supply & fit) depending on size and block style.

Are glass brick walls expensive?

Compared to a standard stud partition, glass block walls cost more upfront. This is mainly because the blocks themselves are pricier than plasterboard. But they're durable, low-maintenance, and add light to a space in a way a solid wall can't.

What are the disadvantages of a glass block wall?

Glass block walls are heavier than stud partitions (important for floor loading), can't be opened for ventilation, and are harder to modify once built. They also offer limited thermal insulation unless you choose specialist thermally enhanced blocks.

Why aren't glass blocks used anymore?

Glass blocks were less fashionable through the 2000s and 2010s, but are now popular again in bathrooms, side-return extensions and kitchen-diners as a way to add privacy and diffuse light.

Are glass block showers out of style?

After dipping in popularity, glass block shower walls have come back as a contemporary design choice, particularly in minimalist and industrial-style bathrooms. The key is choosing a clean, modern block pattern (wave or frosted) rather than the heavily patterned styles from the 1990s.
