Carpet tiles will not work on the stairway. It needs actual type carpeting. Why carpet tiles anyway, even in the bedroom. Maybe vinyl planking, would be a better choice, or have regular carpeting the same color up through the whole upstairs, and down the steps. Its hard to tell in your picture, but, whats wrong with the carpet that is there?

The Carpet is 10 year old so, want to change it . Also, we have small kids coz of which want to keep the carpet. As I want to do it by myself, so carpet tiles seems to be easy diy as compared to regular carpet installation.

Any suggestion on what should I do with the stairs then .

Presuming they are builder grade unfinished stairs you will have to pay a carpet store to get them re carpeted. If you haven’t priced out carpet tiles they add up fast, get a price on professional installation of broadloom and see how it compares.

Bedroom1 = 18 12 ft
Bedroom2 = 14 10 ft
Bedroom3 = 10*10 ft

I took the quote and it was ~$12,000 CAD for bedroom and stairs. I did a quick calculation if I use carpet tiles and diy, its coming out to be ~~$2500 for 3 rooms and open space(not stairs).

But it's awful $2500 quality carpet, with no stairs. Stairs are a HUGE cost to get done because they are so difficult. They are not at all DIY, unless you want the worst result in the world. Carpet tiles are not suitable for stairs either. You have some really jacked up priorities.

That way I am looking for suggestions for the stairs. What are the alternatives? $7000 extra for carpet is a big amount for me , can’t afford .

I hope you come back and read this.

It's tough when we're just getting started in life with a young family, and most folks have to watch their spending carefully. You sound like a great dad to me, wanting to protect your little ones from hard staircases and to keep their dear little feet from the cold floors in their bedrooms. Carpet tiles are great for that. Read lots of reviews and then go view in person, and buy in person if you can (lots of tales of woe about deliveries that didn't come or damaged merchandise or mismatched color -- but also many happy customer reviews too). You're also already thinking outside the box, which is the beginning of a great creative DIY future. There are economical stairs solutions. There are many step-by-step DIY blog posts, images, and YouTube videos where everyday folks have made amazing and gorgeous transitions for their stairs for little money, so spend a little time online getting inspired, learning and seeing what's possible. I did my own staircase and I love how it turned out and have gotten many complements on it. Maybe first see if you can find a carpet remnant store in your area, then see if there is a big enough carpet piece you like. Then give them your stairs measurements and ask what they would charge to install. Maybe 6-7 years ago I got my 13 split entry stairs carpeted for $400, and I don't live in a cheap area. I've seen warehouses around here full of carpet rolls they're selling on Craigslist, and there are installers on that site too. So poke around a bit and make some calls. I got all my hardwood flooring and installation there from Craigslist with a great deal. If you're totally on your own, remove the carpet. Remove the kazillion staples, padding, etc. Spackle the holes. Sand. Then prime, then paint the stairs (probably brown to match the wood) and put several coats of Minwax Polyurethane on them to protect the paint. That will yellow a bit over time but you won't notice it over brown (when protecting white or any pale color that might show yellowing, use Polycrylic instead). Then go look online for carpet treads for stairs. There are lots that aren't expensive. There are even some that cover the bullnose, which would make them the equivalent of fully carpeted stairs in regards to cushioning falls for yourself and your loved ones. All you do is peel and stick. Don't despair. You can learn to do anything. Please post pictures of what you do so we can tell you how smart and clever you are, and you can inspire others.
