3/16 difference in subfloor?

installing wide-plank laminate flooring in an open floor-plan house. Problem is the kitchen had vinyl and living room and dining room had carpet with different thickness of underlayment. There's a 3/16" difference between the height of the subfloors, and about an 8foot wide area of transition between the rooms. I want the new floor to flow throughout the entire house seamlessly and don't want to use any t-mold type transition joints.

I'm planning on getting some 3/16" underlayment to bring the subfloors up to the same height...... unless there's some other way.

Can I just step-down the transitions over 8 feet or so by using stick-down tiles, or something? Probably stupid questions, but I'd rather ask before doing two rooms with new underlayment then finding I didn't need to do it.

Thanks

If you want it to flow, bottom line, the subflooring must be the same height. Adding the 3/16 would accomplish it.

How much subfloor panels do you need? Your idea with the tiles may work as laminates are supposed to be able to go over the height of 1 layer if vinyl. So spreading out where it steps down between layers over the whole 8 foot span between the rooms may work too. It may be cheaper to use patch to skim out the height difference over the 8 foot span.
approx. $80 for patch, $? for tiles or underlayment.

I went with 3/16 underlayment. It took 15 sheets @ $11 per sheet, but ended up with perfectly level transitions.
