can this be used in a shower to cover ugly holes in tiles

The main use for these items is to repair/cover damage on a timber door. They are only grade 304 which means they may not be suitable for use in a shower room as they might rust in the environment. You can contact our sales team on either 02072281185 or sales@sdslondon.co.uk as we may be able to provide a bespoke item made in grade 316 stainless steel.
