I have 3 glass doors installed in my house. 2 in the kitchen and 1 at my MBR bathroom. Doors can be expensive and cost a bomb to your renovation budget, thus choose the right design carefully and wisely.
Costs:1) Hinged glass door at the entrance to backyard (clear without matte finished) - $400
(exclude sticker - sticker cost $2 from Daiso)
2) Sliding glass door at the entrance to kitchen (clear without matte finished) - $600
(exclude sticker - sticker costs around $10)
3) Hinged glass door for MBR toilet (matte finished) - $450
(Price listed above are direct price from factory, you might want to mark up a bit if yours are from ID or contractor)
How to save cost:
1) Buy direct from factory, I got mine from a glass factory in Marsiling
2) As you can see, matte finished is more expensive than clear glass door, unless the door is installed for toilet, you can choose clear glass door and decorate it with some stickers. The reason I put stickers on the glass door is to avoid people from banging against the door when it is closed, it is especially dangerous for sliding door, funny, but it really happen in my old house before, when the door is closed, you can't really see that it is closed or open..... Besides, the sticker also made my doors looked elegant, don't they?
Pros of glass door:
1) The pro is of course it looked more classy and elegant, definitely better than the wooden doors.
2) It creates spaces for small room, not only the sliding door, even the hinged door make you feel your room is bigger, the effect is just like those glass windows.
3) It is easier to maintain the cleanliness compare to the wooden door, no wear and tear on the door except on the hinge.
Cons of glass door:
1) Cost more expensive than wooden door
2) Need extra care not to bang the door (although it is tempered glass)
3) The hinge might give sounds over time as the door is heavy
4) High repair cost if any of the hinge spoilt
5) Need timely cleaning if not will have visible finger prints etc
Maintenance:
Just wipe with damp cloth will do, once a month. For door installed in Kitchen, you might need to use some detergent when cleaning and wiping, as the oil will stick on the door due to cooking, but still it'll be easier to clean compare to wooden door.
