Ditto! Lol. Carpet is much quieter and safer (I've slid down my previous 'all wooden' steps before now!) but I hate it too. If you have good treads, I'd go for a stylish runner which looks nicer. Get a busy pattern ie stripes or funky geometries to keep the dirt less obvious.

cover the tiles with something thin such as Amtico

My company specialises in renewing and upgrading existing stairs as well as designing and making new ones. Here's a project that we completed at the end of 2016, the first pictures are how the stairs looked when we first visited and the last ones with the glass are how we changed it. Here's the review from our client who was very pleased http://bit.ly/2oYjRFi . All our work is designed and made in house so you don't have to bother with taking templates to a local glazier. As you have seen from the number of replies the range of options are unlimited. Most things can be achieved with the right client and good budget but to avoid spending too much on something you don't need it is important to gain an understanding of how you want the whole house to look; I always request that my clients show me images of things they like, furniture, interiors so that a design can be developed that not only complements the design/ concept of a home but enhances. Depending on your budget, you could make a saving by just renewing the stairs in a design that incorporates a glazed banister and fixes the issues that you are concerned about. Site installation work is far more expensive than just making something from scratch in our workshop. I don't believe you have any problems offering B&B with the stairs as they are as far as Building Regs go. What you should probably take account of though is providing a staircase for the guests that they are comfortable with and feel safe using, if you are certain that all the guests will be fully mobile adults then in the strict reading of the regs your stairs will comply anyway. Building Regs approved document K requires gaps in staircase risers and banisters to be 100 mm or less to provide adequate safety for children. Following this, but also keeping open risers means adding a small downstand underneath the tread to reduce the open riser height. It will also pose problems adding glass to the side of your existing flight because you will have difficulty because there are not convenient points to fix the glass, nor have the carriages - the beams supporting the treads underneath - been designed to carry the additional load from the glass or stair users pressing on it, so additional structure must be added to the carriage to carry the glass, everything is possible but most people have a budget so I must ask you - What is yours?

This was a very difficult staircase to build but this finish product is amazing
