I installed tongue and groove wood flooring in our house starting in a front bedroom and transitioned across the hall into the bedrooms on the other side and out into the living room with no transition strips. All it took was paralleling the center of the hall way to the starting point.

A click together floor - especially vinyl because it is thin and the click systems are vulnerable to damage - can be VERY difficult to lay in the "wrong" direction. It can double or triple the time to install when working backwards.....and be prepared for TWICE the "waste" when working backwards.

If you want 2400sf of transitionless flooring then you REALLY need to pay the piper and GLUE IT DOWN.

Yep. Glue down gets you want you want - cost will double for install....but you get away from transitions and you don't worry about working backwards.

Glue down vinyl planks are WITHOUT the click edge....so there's no worry about which direction you need to work. Cost will be a factor.

Some click together vinyl can have issues with "transitionless" spaces...while others do not. Some will advertise they have no problems when in fact they do. Large installs with vinyl on multiple levels/etc this gets very tricky to do it without transitions.

And to be clear, transition strips are fairly cheap compared to a full glue down install. And it might be cheaper to use transitions than paying for MORE flooring (because of the waste/damage when installing backwards) and longer installation times (labor costs go up when you work "slowly").

There are some professionals who might not even attempt the "backward" install because they don't want the hassle, nor do they want to be blamed for damaging ALL THOSE PLANKS.

Just a little FYI. If you REALLY MUST HAVE the "transitionless" floor - pay the piper and have it glued into place.

Thank you for the help. After weeks of scraping glue with embedded river mud off all floors, we are not using anything that attaches to the slab again. I hope to find some stores with loose samples that I can work with to see if anything fits my needs.

Seb225, I have "backfilled" at several of my homes with various click laminates (especially closets seem to fit this situation). My most recent installation was of Coretec, which also can be "backfilled". I'm a DIY middle aged female so if I can do it you can. You may have to take some samples home and play with them, some of the click systems might work better at this than others.

Another issue is, how many square feet does the manufacturer say you can install without a transition for expansion?? 2400 may be too much. If you can run it all seamlessly it will look fantastic!! If you can't because of manufacturers guidelines, try and put the transitions where they're less noticeable (doorway of spare bedroom for example).

You also might consider a brand that connects with an adhesive flange -- like the Konecto Aspire line. I think a few other brands have similar.

I'm in a similar situation due to hurricane Sally. I'd love to know how this ended and how your floors look today. Do tell, please!

We're in the process of doing this in `1300 sf. It does take longer and you have to be more careful, but it's not all that complicated or difficult, and contrary to Cancorks answer, we haven't damaged ANY planks. Most of the pro videos show the installers joining the planks end-to-end first then gently working that entire row into the back side.
