Tubular Deadbolts — UK Privacy Solutions

Choosing Sizes, Spindles & Finishes (Bathroom, En-Suite & WC)

For a modern bathroom door layout using door handles on a rose and a separate bathroom turn & release, tubular deadbolts deliver discreet, reliable privacy.

In most UK installations, the 3” tubular deadbolt is preferred, keeping the bathroom turn neatly in line beneath the handle. Depending on your handle position and latch length, 2.5”, 4” or 5” sizes can also be suitable. UK-standard followers are typically 5 mm, while certain commercial sets use 8 mm.

Popular finishes — satin stainless, polished chrome, antique brass — allow you to match with door furniture and premium accessories for a consistent look.

These privacy bolts are ideal for bathrooms, en-suites, and WCs, and are not intended for exterior security. UK-wide supply covers London, Manchester, Birmingham, Leeds, Glasgow, and Edinburgh.

Tell us your door thickness, handle position, and preferred finish, and we’ll advise the best tubular deadbolt for neat alignment and smooth operation.

In the UK, 3" is by far the most popular size. The 4” and 5” options are generally chosen when matching with latches used alongside mortice knobs, helping to position the handle and bathroom turn centrally within the stile of the door.

All privacy bolts are supplied to suit the standard UK spindle size, and the spindle is included with the bathroom turn.

We support domestic and commercial projects across the UK, including London, Manchester, Birmingham, Leeds, Glasgow, and Edinburgh.

Frequently Asked Questions

What size tubular deadbolt should I use for a UK bathroom door?

A 3” tubular deadbolt is the most common choice for UK bathrooms as it aligns the turn neatly below the handle. 2.5”, 4”, and 5” options are also available for different door layouts. You can browse our full Tubular Deadbolts range for all sizes.

Will a tubular deadbolt work with standard UK bathroom turn and release sets?

Yes. Most tubular deadbolts use a 5 mm spindle follower compatible with UK-standard bathroom turn & release sets. Some commercial variants use 8 mm.

Is a tubular deadbolt suitable for exterior doors?

No. Tubular deadbolts are designed for internal privacy (bathrooms, en-suites, and WCs) and should not be used for external security. For security applications, view our Locks & Latches category.

How is a tubular deadbolt different from a mortice bathroom lock?

A mortice bathroom lock includes both a latch and a bolt operated by a handle and thumbturn. A tubular deadbolt is just the bolt, offering a simpler, faster fit with a separate turn & release.

Which finishes match common UK door furniture?

Popular finishes include satin stainless steel, polished chrome, and antique brass, allowing you to coordinate with your door furniture and accessories.
