Hi there. I believe you have a centrifugal 100mm bathroom fan. The DX100 is a 100mm fan and would therefore fit in the space in the same way, but it is an axial fan. The thing to consider is how long your duct run is. If it's less than 2.5m long, then the DX100 will do a good job, and best results will be at it's highest setting. If the ducting is over 2.5m then an alternative centrifugal fan would be the best solution for a fan that fit's in the same way. Beyond this for high extraction needs, you might consider an inline fan, but these are mounted in the loft or ceiling space, so would require a new installation. I hope this helps.
