All our shabby chic wall tiles are suitable for kitchens, bathrooms, or utility rooms. They are all fully waterproof, but not advised for use where they will have prolonged contact with water, such as in a shower enclosure. They are finished with a none toxic and none flammable surface. You will receive full instructions for usage and maintenance with your purchase, and this information is printed on each listing also. Most designs are available in 98mm or 148mm, but some are only in one size, which is clearly laid out on the listing. They were originally HR Johnson tiles which are made in the UK. If you require any other sizes/makes of tiles, please get in touch at firstname.lastname@example.org, and we will be more than happy to discuss your requirements and put together a personal quote for you. From time to time we may have small sets of tiles that are already made and have been used for display purposes. These will be displayed in our "Ready to dispatch immediately" section and will generally be sold with a reduction.
