Is Your Shower Glass Around 6mm?
6mm shower glass is common on many UK shower doors and bath screens. It sits at the upper end of the 4–6mm shower screen seal range, so choosing the correct profile and gap size is still important.

6mm Shower Door Seal FAQ
Common questions about choosing replacement shower door seals for 6mm glass, standard UK shower doors and 4–6mm compatible profiles.
Is 6mm glass common for UK shower doors?
Yes. 6mm glass is commonly used on many UK shower doors, bath screens and frameless shower panels. It sits at the upper end of the 4–6mm replacement shower seal range.
If your glass measures around 6mm, choose products marked for 4–6mm glass, then check the seal profile, fitting position and gap size before ordering.
Can a 4–6mm shower seal fit 6mm glass?
Yes, if the product is designed for 4–6mm glass. Many push-fit shower door seals are made to grip this range, including 6mm glass.
The fit also depends on the seal shape and where it is installed, such as the bottom edge, side edge, curved screen or magnetic closing edge.
Will a 4–6mm shower seal be too tight on 6mm glass?
It may feel firmer than on thinner glass because 6mm sits at the upper end of the 4–6mm range. This is normal for many push-fit seals.
If it is very difficult to fit, check that the glass edge is clean and that you have measured the glass itself, not the old seal, limescale build-up or a raised edge.
How do I choose the right 6mm shower door seal?
First choose by fitting position. Use a bottom seal for water leaking under the door, a vertical seal for side gaps, a magnetic seal for glass-to-glass closure, or a curved seal for quadrant and P-shaped screens.
Then measure the gap the seal needs to cover and compare your old seal profile with the product images before ordering.
Which 6mm shower door seal stops water leaking at the bottom?
For water leaking under a 6mm shower door, choose a bottom shower seal with a soft fin or drip rail.
Measure the gap between the bottom of the glass and the shower tray or bath rim, then choose the closest fin length, such as 12mm, 16mm, 20mm or 23mm.
What if my shower glass measures more than 6mm?
If your glass is clearly thicker than 6mm, do not force a 4–6mm seal onto it. Thicker glass usually needs a different channel size.
If your measurement is closer to 8mm or 10mm, compare our 8mm shower door seals or 10mm shower door seals before ordering.
Can I use an 8mm shower seal on 6mm glass?
Usually no. An 8mm shower seal is likely to have a wider channel and may not grip securely on 6mm glass.
If your glass measures around 6mm, choose a product marked for 4–6mm glass unless the product description clearly says otherwise.
Do 6mm shower doors need magnetic seals?
Only if the door closes against another glass panel and uses magnetic contact to stay shut. Magnetic shower door seals are used for pivot, corner and some bi-fold shower doors.
If your issue is water leaking under the door, a magnetic seal will not solve it. You will need a bottom seal with a fin or drip rail instead.
Do I need glue or silicone for a 6mm shower door seal?
Most push-fit 6mm shower door seals do not need glue or silicone. Clean and dry the glass edge before fitting so the channel can grip properly.
Only use adhesive if the product is designed as a self-adhesive shower seal.
Tip: 6mm glass is the upper end of the 4–6mm seal range. If your glass is clearly thicker than 6mm, check the 8mm or 10mm range instead of forcing a 4–6mm seal to fit.
