Enter the room while building a shinespark and use it on the lowest part of the ramp to cross the room and reach a raised ledge on the right side wall. From there, use SpaceJump to escape the water. Carry the shinespark to the bottom of the ramp by delaying the first Choot with two Power Beam shots, killing it, or bounceballing through it. The Choot can be shot diagonally from the middle platform, and again by running off that platform and aiming down to float above it.

Enter the room while building a shinespark and use it on the lowest part of the ramp to diagonally spark up and out of the water. Unmorphing with the correct timing and positioning for the Shinespark are very precise, and there are no extra frames on the Shinespark timer to work with. Carry the shinespark to the bottom of the ramp either with a bounce ball which takes damage from the Choot, or delay the first Choot with two shots and then use a late mockball. Then shinespark up and use SpaceJump to reach the door.

BounceBall into the Lava, Unmorphing with good timing to sink faster and drift effeciently towards the bottom right Namihe. Walljump at about eye height (4 pixel window) to gain enough height to reach the center portion of ceiling. While rising, wiggle to shrink Samus' hitbox. Some walljump positions will not need to wiggle, when walljumping far away from the Namihe. Jumping, from the wall, around the next lowest overhang is very precise and taking any extra time to position will increase the amount of lava damage being taken. It may help to disable HiJump for this part. Then Walljump again to exit the Lava and reach the left ledge.
